Description

recording device

technical field

The present invention relates to a recording device such as an inkjet printer that performs recording by ejecting ink droplets onto a recording material such as recording paper, and to a liquid ejecting device that makes a liquid adhere to the material to be ejected.

Background technique

Here, the liquid ejecting device includes not only recording devices such as printers, copiers, and facsimiles that use an inkjet type recording head to eject ink droplets from the recording head to record on a recording material, but also include: instead of ink, from equivalent A liquid ejecting head of the recording head ejects a liquid corresponding to other purposes to an ejected material corresponding to a recording material, and causes the liquid to adhere to the ejected material. As the liquid ejection head, in addition to the above-mentioned recording head, toner ejection heads used in the manufacture of color filters such as liquid crystal displays, and those used in the formation of electrodes in organic EL displays and surface emission displays (FED) etc. Electrode material (conductive paste) injection head, bioorganic material injection head used in biochip manufacturing, sample injection head as a precision pipette, etc.

As one type of liquid ejecting device for a recording device, there is an inkjet printer. This inkjet printer is provided on the upstream side of the recording material conveyance path, and conveys the recording material (for example, plain paper, postcards, envelopes, etc.) held in an oblique posture to the downstream side one by one. A material conveying device; a recording head that is disposed on the downstream side of the recording material conveying device and ejects ink droplets to the recording material; is disposed on the downstream side of the recording head and discharges the recorded material that has been recorded discharge roller. The discharge roller is composed of the following parts: a discharge driving roller arranged on the non-recording side (i.e., the back side) of the recorded material; ), a discharge drive roller consisting of a toothed roller having a plurality of teeth on its outer periphery;

However, recent inkjet printers are configured to record on various recording materials such as postcards, envelopes, cardboard, and CD-R (Compact Disc Rewritable) in addition to plain paper.

Among these to-be-recorded materials, when recording on plain paper, postcards, envelopes, etc., which are flexible and can be conveyed in a curved posture (hereinafter referred to as "paper"), the recording-to-record conveying device is used. Conveyance, after recording by the recording head, is discharged by the discharge roller to the first conveyance path that conveys the paper in one direction in the recording material collector provided on the front side of the device (the downstream side of the conveyance path). However, when recording on rigid materials such as cardboard and CD-R (hereinafter referred to as "rigid recording material"), it is difficult or impossible to convey through the recording material conveying device, so the front of the device is used. The recording material collector conveys the rigid recording material G to the recording head for recording, and then discharges the rigid recording material G to the recording material collector.

When recording on a CD-R using the second transport path, it is necessary to prevent the eject follower roller from coming into contact with the CD-R. This is to prevent contact traces caused by the contact between the discharge driven roller made of toothed rollers and the recording surface of the CD-R, that is, the upper surface, and the impact on the data storage layer due to contact (for example, when data is stored). , the data is destroyed, and when no data is stored, data cannot be stored at the contacted part).

Therefore, there has been proposed a recording device that displaces the discharge driven roller according to the purpose of printing (for example, refer to Japanese Patent Laid-Open No. 2002-192782). That is, when the paper discharge driven roller is attached to the paper discharge frame and the paper discharge frame is displaced to record on paper such as plain paper, the paper discharge driven roller is kept in contact with the paper discharge drive roller. When recording on a rigid recording material such as a CD-R, the state in which the discharge driven roller is kept away from the discharge drive roller is maintained.

In addition, when using the second transport path to record on rigid recording materials such as CD-R, an operating lever is provided on the device to avoid the paper output frame.

However, when printing is performed on a rigid recording material, it is cumbersome to operate the operation lever, and when the user erroneously operates the operation lever to perform printing on a rigid recording material, the above-mentioned problems will arise.

Detailed ways

Hereinafter, an embodiment of the present invention, a recording device, and a liquid ejecting device will be described in the following order by taking an inkjet printer as an example with reference to the drawings.

1. The overall structure of the inkjet printer;

2. The structure of the displacement connection mechanism of the discharge frame;

3. The structure of the transmission driven roller displacement connection mechanism and the roller interval displacement connection mechanism.

<1. The overall structure of the inkjet printer>

First, an overall configuration of an inkjet printer (hereinafter referred to as "printer") 1 of this embodiment will be described with reference to FIGS. 1 and 2 .

Here, FIG. 1 is a side view of the printer 1 with a part omitted, showing a state of printing (recording) on paper P using a first transport path ① described later, and FIG. 2 is a side view of the same printer with a part omitted. The figure shows the state of printing (recording) on the rigid recording material G using the second transport path ② described later.

Here, as the second recording material to be recorded in a state of being in contact with a discharge driven roller as a discharge driven roller described later, the paper feeding device 2 used as a recording material conveying device described later can be The recording material conveyed in a curved posture (for example, plain paper, postcards, envelopes, and other curved recording materials) is referred to as "paper P", and is used as the paper output from the output driven roller described later. The first recording material that is recorded in the non-contact state of the moving roller, the recording material that is difficult or impossible to convey in a curved posture (for example, CD-R, cardboard and other rigid recording materials) is called "rigid". Recorded material G", sometimes they are collectively referred to as "recorded material".

As shown in FIG. 1, the printer 1 is provided with a paper feeder 2 for feeding paper P on the upstream side of the recording material conveyance path on the rear side of the device (in FIG. 1, the right-hand side of the paper), and has: The paper feeding device 2 stacks and holds the paper P in an inclined posture, bends one by one, and conveys it downstream. The first transport path ① for transporting the paper P in one direction discharged in a horizontal posture; as shown in FIG. The head 13 transports and prints, and then discharges from the front side of the device to the second transport path ② that transports the rigid recording material G to and fro.

In addition, as will be described later, the recording material collector 50 is structured such that it can be displaced so that the second position set when using the first conveying path ① and the second position set using the second conveying path ② can be obtained. 1 position.

First, with reference to FIG. 1 , the operation along the first transport path ① will be described. At this time, the recording material collector 50 is at the second position.

The paper feeding device 2 has a paper stocker 16 and a D-shaped paper feeding roller when viewed from the side. The stocker 16 can hold a plurality of sheets of paper P stacked in an inclined posture, and can press and separate the paper feed roller 14 by swinging around a swing fulcrum (not shown) provided on the upstream side. The paper feed roller 14 is rotatable about the rotation shaft 14a, and its surface is made of a high friction material, so that the paper P that comes into contact can be reliably conveyed.

The paper P set in the paper stocker 16 is pressed up by the pressing operation of the paper stocker 16 against the paper feed roller 14 , and the uppermost layer of paper comes into contact with the paper feed roller 14 . In the contact state, the uppermost paper P is separated from the paper P below it by the rotation of the paper feed roller 14, and is conveyed downstream.

A paper guide cover 15 is disposed substantially horizontally below the downstream side of the paper feed roller 14 , and guides the paper P conveyed from the paper feed device 2 to the downstream side.

On the downstream side of the paper guide cover 15, a conveyance drive roller 19a provided on the non-recording surface of the paper P (that is, the back side of the paper P) and rotationally driven by a driving member not shown and a transport drive roller 19a provided on the paper P are disposed. The conveying roller 19 is constituted by a conveying driven roller 19 b which is driven to rotate on the side of the recording surface of the paper P (that is, on the surface of the paper P) and in contact with the conveying driving roller 19 a. The conveyance driving roller 19a is composed of a long rod-shaped roller in the main scanning direction (in FIG. 1 , the front-back direction of the paper surface) perpendicular to the conveyance path of the paper P, and one conveyance driven roller 19b is short in the main scanning direction. , and a plurality of them are arranged at given intervals in the main scanning direction. The paper P is precisely conveyed by being nipped by the conveying rollers 19 having such a structure.

The conveyance driven roller 19 b is rotatably supported on the downstream side of the conveyance driven roller holder 18 . The conveying driven roller holder 18 is capable of swinging around the rocking shaft 18a, and is always leaned against the conveying drive roller 19a by a spring as a biasing member. With such a structure, the paper P can be pinched accurately, the conveying force can be provided, and the paper P can be reliably and accurately conveyed.

Above the upstream side of the conveyance driven roller holder 18 , a cam member 36 rotatable about a cam rotation shaft 31 is arranged as a member for oscillating the conveyance driven roller holder 18 . The cam rotation shaft 31 is controlled by the rotation of the conveying driven roller displacement connection mechanism 200 described later. By rotating the cam rotation shaft 31, the cam member 36 is brought into contact with the cam follower 18b, and the conveying slave is resisted against the abutting force. Moving roller support 18 shakes.

According to such a structure, by shaking, the conveyance driven roller holder 18 can take the state where the conveyance driven roller 19b is in contact with the conveyance drive roller 19a (see FIG. 1 ) and the separated state where the conveyance driven roller 19b is separated from the conveyance drive roller 19a. (Refer to Figure 2).

A recording section for printing is formed near the downstream side of the transport roller 19 . The roller 28 and the recording head 13 are disposed facing each other up and down in the recording section. The roller 28 is long in the main scanning direction, and can support the conveyed paper P from below (non-recording surface side).

The recording head 13 is mounted on the bottom of the carriage 10 . The carriage 10 is supported on a carriage guide shaft 12 extending in the main scanning direction (width direction of the paper P), and reciprocates along the carriage guide shaft 12 . In addition, the carriage 10 has removable ink cartridges 11 such as yellow, magenta, cyan, and black, and while moving back and forth along the carriage guide shaft 12, ink droplets of these colors are ejected from the recording head 13, enabling color printing.

In addition, the carriage guide shaft 12 is linked with the recorded material collector 50 through the cylinder interval displacement connection mechanism 300 described later, and can be displaced in the direction (up and down in FIG. 1 ) orthogonal to the cylinder 28. When paper P or rigid recording material G is used as the recording material, the distance between the recording head 13 and the cylinder 28 can be adjusted by changing the position according to the thickness of the recording material (the so-called cylinder gap. Hereinafter, it may be expressed as "PG") .

That is, since the recording quality is largely influenced by the paper gap of the distance between the recording surface of the recording material conveyed on the drum 28 and the recording head 13, the size of the drum gap is set in consideration of the paper gap.

Thus, when printing on the paper P, the carriage 10 becomes closer to the roller 28 (hereinafter referred to as "N position"; refer to FIG. 1 ), and a relatively small PG is set. When printing on the rigid recording medium G, the carriage 10 is in a state farther from the N position than the N position (hereinafter referred to as “++ position”; refer to FIG. 2 ), and a relatively large PG is set. In addition, in the following description, the roller interval set when the carriage 10 is in the N position may be expressed as "PG normal", and the roller interval set when the carriage 10 is in the ++ position may be expressed as "PG++".

On the downstream side of the recording unit is the discharge unit for the paper P. As a discharge mechanism, a discharge drive roller as a discharge drive roller and a discharge follower roller as a discharge follower are provided as a pair of discharge rollers. discharge roller. More specifically, there is provided: a first discharge roller composed of a first discharge driving roller 21a and a first discharge driven roller 21b, which is disposed near the downstream side of the opposing position of the recording head 13 and the cylinder 28. 21. The second discharge roller 22, which is arranged on the downstream side of the first discharge roller 21, is composed of a second discharge drive roller 22a and a second discharge driven roller 22b. In addition, in the following description, the first paper discharge roller 21 and the second paper discharge roller 22 are collectively shown as paper discharge rollers (21, 22), and the first paper discharge driving roller 21a and the second paper discharge driving roller 22a are They are collectively shown as discharge drive rollers (21a, 22a), and the first discharge driven rollers 21b and second discharge driven rollers 22b are collectively represented as discharge driven rollers (21b, 22b).

The paper discharge driving rollers (21a, 22a) are arranged on the non-recording side of the paper P (that is, the back side of the paper P), and are composed of a rod-shaped roller extending in the main scanning direction with a rubber material provided on its outer periphery. The unillustrated driving part is rotated and controlled.

On the other hand, the discharge driven rollers (21b, 22b) are arranged on the recording surface of the paper P (ie, on the front side of the paper P), and are constituted by toothed rollers having a plurality of teeth on the outer periphery. Furthermore, it is rotatably attached to the discharge frame 40 in a state protruding downward (that is, to the conveyance path of the recording material).

The paper discharge frame 40 can be linked with the recorded material collector 50 through the paper discharge frame displacement connection mechanism 100 as the "connection mechanism" described later, and can be displaced, thereby obtaining: paper discharge driven rollers (21b, 22b) The state of being located in the transport path of the recording material, that is, the state in which the ejection driven rollers (21b, 22b) are in contact with the ejection driving rollers (21a, 22a) (see FIG. 1); the ejection driven rollers (21b, 22b) 22b) A state outside the conveying path of the recording material, that is, a separated state in which the discharge driven rollers (21b, 22b) are separated from the discharge driving rollers (21a, 22a) (see FIG. 2 ). That is, the structure of the paper discharge frame 40 is such that the approach state (corresponding to the contact state) in which the paper discharge driven rollers (21b, 22b) are located in the recording material conveying path, that is, directly above the recording material conveying path, can be obtained. state) above the approaching state, and the separation state (state corresponding to the separation state) in which the discharge driven rollers (21b, 22b) are separated from the recording material conveyance path. The paper P is discharged to the recording material collector 50 by the paper discharge rollers ( 21 , 22 ) having such a structure.

Next, referring to FIG. 2 , a description will be given of a situation when printing is performed on the rigid recording material G using the second transport path ②. At this time, by setting the recording material collector 50 to the first position and making the recording material carrying surface 51 on the upper surface of the recording material collector 50 nearly horizontal, a straight line leading to the bottom of the recording head 13 is formed. Conveyance and discharge path of the rigid recording material G. In addition, through the paper discharge frame displacement connection mechanism 100 described later, it is linked with the recorded material collector 50, so that the paper discharge frame 40 is in a separated state, and the paper discharge driven rollers (21b, 22b) are moved to the position corresponding to the rigidity of the recorded material. The position where material G does not touch. Thereby, printing can be performed without contacting the output driven rollers (21b, 22b) with the rigid recording material G.

In addition, the conveyance driven roller 19b is separated from the conveyance driving roller 19a by a conveyance driven roller displacement connection mechanism 200 described later. This prevents the rigid recording material G from colliding with the conveyance driven roller 19 b, and precisely conveys the rigid recording material G while being pinched by the conveyance rollers 19 .

Through the roller interval displacement connection mechanism 300 described later. Linked with the recording material collector 50, the carriage 10 is at the ++ position, which can avoid contact between the rigid recording material G and the recording head 13, and adjust the roller interval corresponding to the rigid recording material G.

In this way, under the state that the rigid recording material G can be conveyed linearly, the rigid recording material G is set on the recording material collector 50, and is lowered toward the recording head 13 along the recording material carrying surface 51 (that is, the recording portion ) is inserted into the rigid recording material G, and printing is performed after performing an outcropping operation. In this way, printing can be performed while avoiding contact between the rigid recording medium G and the discharge driven rollers (21b, 22b).

In addition, when the rigid recording medium G is an optical recording medium such as a CD-R that cannot be conveyed directly, recording is performed while being set on a dedicated tray (for example, a tray formed with a recess for fitting the CD-R).

<2. The structure of the displacement connection mechanism of the discharge frame>

Next, referring to FIGS. 3 to 8 , the discharge frame displacement connection mechanism 100 for displacing the discharge frame 40 between the contact state and the separation state by displacing the recording material collector 50 will be described.

Here, FIG. 3 is a side view of main parts used in the description of the discharge frame displacement connection mechanism 100 of this embodiment, and FIG. 4 is a perspective view of main parts showing the same state as in FIG. It is the second state. In addition, FIG. 5 is a side view for explaining the main parts of the discharge frame displacement connection mechanism 100 of this embodiment, and FIG. 6 is a perspective view showing the main parts in the same state as in FIG. The state at the first position. In addition, FIG. 7 is a perspective view of the main part of the periphery of the guide cover 80 disposed near the base end portion of the recording material collector 50 viewed from the upper side of the downstream side, and FIG. 8 is a view of the periphery of the guide cover 80 viewed from a different angle from FIG. A perspective view of the main parts. 3 to 8 show the device right side of the recording material collector 50 when the printer 1 is viewed from the front side of the device, and FIGS. 3 to 6 show the state of the printer 1 viewed from the right side.

The recording material collector 50 disposed on the front surface of the printer 1 can be displaceable, so as to obtain: the rigid recording material G can be linearly conveyed from the nearly horizontal recording material bearing surface 51 to the recording head 13, And the first position (refer to FIG. 5 and FIG. 6 ) of the linear conveying and discharging path that is discharged linearly from the recording head 13 to the recording material carrying surface 51: the paper P that is conveyed by the paper feeding device 2 and printed is discharged. The stacked second position is lower than the first position and the recording material carrying surface 51 is slightly inclined (see FIGS. 3 and 4 ).

The discharge frame displacement connection mechanism 100 has an unlocking handle auxiliary body 55 , an unlocking handle 60 , a rotating shaft 63 and a connecting frame 68 . On both sides of the upstream side (that is, the base end side) of the recorded material collector 50, a pair of fitting shafts 52 are provided, and one side of the fitting shafts 52 is formed on the inner side wall of the unlocking handle auxiliary body 55. The bearing part (not shown) supports it. Thus, the recording material collector 50 can swing about 90 degrees around the matching shaft 52, and can obtain a near-horizontal use state that can be obtained when the printer 1 is in use and a nearly vertical storage state that can be obtained when not in use (not shown in the figure). Show). When the recording material collector 50 is stored, it is possible to reduce the loading area when the printer 1 is not in use. In addition, the other side of the engagement shaft 52 is supported by an operating member 90 (refer to FIG. 9 ) which will be described later.

The unlock handle auxiliary body 55 supporting the engaging shaft 52 can follow the displacement of the first position and the second position of the recording material collector 50, and move in the vertical direction of the device. More specifically, as shown in FIG. 7 , the unlocking handle auxiliary body 55 is guided by the inner wall surface of the guide cover 80 disposed on its outer peripheral portion, and the sheet metal 83 formed of a plate-shaped body extending in the vertical direction protruding toward the front of the device passes through It is also guided in a groove (not shown) extending in the vertical direction formed in the unlock handle auxiliary body 55 at the corresponding position of the sheet metal 83 . With such a structure, the unlocking handle auxiliary body 55 can be accurately positioned in the front, rear and left and right directions of the device when viewed from the front of the device, and can reliably track the movement of the recording material collector 50 in the vertical direction. In addition, a part of the guide cover 80 is disposed on the wall portion 80b between the recording material collector 50 and the unlocking handle auxiliary body 55. As shown in FIG. 80a.

Returning to FIGS. 3 to 6 , a sliding groove 55 a is formed on the unlocking handle auxiliary body 55 . The hub portion 60 a of the unlocking handle 60 is fitted into the sliding groove 55 a, and the unlocking handle 60 and the unlocking handle auxiliary body 55 are interlocked to rotate around the rotation shaft 63 . In addition, the unlocking handle 60 is guided by the inner wall surface of the guide cover 80 , thereby restricting detachment of the hub portion 60 a from the sliding groove 55 a.

The rotating shaft 63 has a cross-sectional D shape, and is embedded in a bearing hole of the same shape formed on the unlocking handle 60 so as to rotate in the same amount and in the same direction as the unlocking handle 60 . The other end of the rotating shaft 63 is embedded in the connecting frame 68 and can transmit the rotation of the unlocking handle 60 to the connecting frame 68 . With such a structure, the rotation of the unlock handle 60 is transmitted to the connection frame 68 through the rotation shaft 63 , and the connection frame 68 can be rotated in the same direction and by the same rotation amount as the unlock handle 60 . That is, the connection frame 68 cannot rotate with respect to the unlock handle 60 , so the connection frame 68 and the unlock handle 60 can be rotated synchronously.

In addition, at both ends of the rotating shaft 63, that is, near the fitting portion with the unlocking handle 60 and the fitting portion with the connection frame 68, a ring 64 having a circular hole passing through the rotating shaft 63 is arranged to support the rotating shaft 63. , making it rotatable, and positioned. In addition, the rotating shaft 63 is not limited to the cross-sectional D shape like the present embodiment, as long as it is a non-circular cross-sectional shape of a triangular or quadrangular equiangular shape, that is, the rotation of the unlocking handle 60 can be transmitted to the The shape of the connection frame 68 can be used without limitation.

The connecting frame 68 cooperates with the paper discharging frame 40 through the matching shaft 69 on the downstream side of the paper discharging frame 40 and can rotate. Thereby, when the connecting frame 68 is rotated about the rotation shaft 63, the state of the discharge frame 40 is changed between the contact state and the separated state.

In addition, the sheet discharge frame 40 is formed of a plate-shaped frame, and is moved downward on the upstream side by a pressing spring 45 provided above it, that is, is brought into a contact state. As a result, the upstream end (free end) of the discharge frame 40 reliably engages with the later-described engaging protrusion, and the discharge frame 40 can be reliably positioned in a contact state. That is, when the discharge frame displacement connection mechanism 100 is in operation, the discharge frame 40 can be separated.

In addition, a guide slope 73 is formed on the side frame 70 to guide the displacement of the discharge frame 40 between the contact state and the separation state. The guide slope 73 has substantially the same shape as the locus that the engaging shaft 69 of the mating portion connecting the frame 68 and the ejection frame 40 can take when the ejection frame 40 is displaced between the contact state and the separated state. In addition, a side J-shaped protrusion 41 that slides on the guide slope 73 is integrally formed on the discharge frame 40 .

According to such a structure, when the paper discharge frame 40 is displaced, the J-shaped protrusion 41 slides along the guide slope 73, so that the paper discharge frame 40 maintains the posture of the contact state, and can change between the contact state and the separation state. bit. Therefore, the paper discharge driven rollers (21b, 22b) mounted on the paper discharge frame 40 can be reliably avoided from the conveyance path of the recording material, and can be moved to a position different from the rigid recording material G such as CD-R. The location of the height of the contact.

In addition, in the present embodiment, a structure in which the ejection frame 40 is maintained in a contact state, that is, a nearly horizontal posture, and becomes a separated state has been described, but the separated state posture is not limited to this. The attitude of the rollers (21b, 22b) away from the recording material conveyance path and not in contact with the rigid recording material G is not limited. Therefore, it is also possible to employ a configuration in which the upstream side of the sheet discharge frame 40 is avoided above the engagement shaft 69 .

On the side frame 70 is formed a fitting protrusion 71 (see FIG. 5 ) for positioning in a contact state with the discharge frame 40 . The engagement protrusion 71 has a protrusion 71 a that contacts the upstream end of the discharge frame 40 , and a frame receiving portion 71 b that supports the discharge frame 40 from below to determine its height.

According to such a structure, the upstream side end part of the sheet discharge frame 40 is positioned by the upstream side by engaging with the engaging protrusion 71 . Moreover, the paper discharge frame 40 leans toward the downstream side by the abutting spring 45 , so it can be reliably and stably matched and positioned with the matching protrusion 71 , and the posture in the contact state can be accurately maintained. In addition, the downstream side of the sheet discharge frame 40 is engaged with the connection frame 68 on the engaging shaft 69 as described above, thereby positioning the height positions of the contact state and the separation state.

Here, by displacing the recording material collector 50 from the second position (see FIG. 3 and FIG. 4 ) to the first position (see FIG. 5 and FIG. 6 ), the state of the discharge frame 40 from the contact state to the separated state will be described. Variable Bit.

When the recorded material collector 50 takes the second position shown in FIGS. 3 and 4 , the discharge frame 40 becomes in contact with the discharge driven rollers ( 21 b , 22 b ) and the discharge drive rollers ( 21 a , 22 a ). state. In addition, the engaging shaft 52 is located at the lower end of the moving path 80a formed on the guide cover 80 shown in FIG. Inside, that is, a plate spring (not shown) provided on the upstream side of the engagement shaft 52 is in contact, and the attitude of the recording material collector 50 at the second position is maintained.

From this state, once the recording material collector 50 is rotated toward the main body of the apparatus about the engaging shaft 52 (clockwise in FIG. 3 ), it becomes a nearly vertical posture, and then lifted up. As a result, the unlocking handle auxiliary body 55 moves upward following it, and the hub portion 60a of the unlocking handle 60 slides along the sliding groove 55a of the unlocking handle auxiliary body 55 from the position 55c to the position 55d. Accompanying this, the unlocking handle 60 turns around the turning shaft 63 (clockwise in FIG. 3 ).

The rotation of the unlocking handle 60 is transmitted to the connection frame 68 through the rotation shaft 63, so that the connection frame 68 rotates in the same direction and by the same amount. As a result, the discharge frame 40 mated with the connecting frame 68 resists the pressing force of the spring 45 and is lifted upward on the downstream side. At this time, the J-shaped protrusion 41 on the upstream side of the discharge frame 40 is also lifted upward along the guide slope 73 on the downstream side, and the discharge frame 40 is displaced to the separated state while maintaining the posture of the contact state.

And, by making the recording material collector 50 rotate to the downstream side, the recording material carrying surface is made into a nearly horizontal posture, the recording material collector 50 shown in FIGS. 5 and 6 becomes the first position, and the paper discharge frame 40 is a separated state where the discharge driven rollers (21b, 22b) are separated from the discharge drive rollers (21a, 22a).

In this way, when the recording material collector 50 is in the first position, the paper discharge frame 40 can be separated, so that the paper discharge driven rollers (21b, 22b) installed on the paper discharge frame 40 can be recorded from the The material conveying path avoids and moves to a height position not in contact with the rigid recording material G. Therefore, printing can be performed without contact between the discharge driven rollers (21b, 22b) and the rigid recording material G, so that problems caused by their contact can be reliably avoided.

Next, by displacing the recording material collector 50 from the first position (refer to FIGS. 5 and 6 ) to the second position (refer to FIGS. 3 and 4 ), the movement of the paper discharge frame 40 from the separated state to the contacted state will also be described. Status changes.

First, the recording material collector 50 is rotated toward the main body of the apparatus (in FIG. 5 , clockwise) around the engaging shaft 52 to become a nearly vertical posture, and then descends downward. As a result, the unlock handle auxiliary body 55 moves downward accordingly, and the hub portion 60 a of the unlock handle 60 slides from the position 55 c to the position 55 d along the sliding groove 55 a of the unlock handle auxiliary body 55 . Accompanying this, the unlock handle 60 rotates around the rotation shaft 63 (clockwise in FIG. 5 ).

The rotation of the unlock handle 60 is transmitted to the connection frame 68 through the rotation shaft 63, so that the connection frame 68 rotates in the same direction and by the same amount. As a result, the discharge frame 40 engaged with the connection frame 68 descends downward toward the upstream side. At this time, the J-shaped protrusion 41 on the upstream side of the paper discharge frame 40 also descends downward along the guide slope 73, and the upstream end of the paper discharge frame 40 cooperates with the matching protrusion 71 to position in contact state. In addition, as mentioned above, the paper discharge frame 40 is moved toward the contact state by the abutment spring 45, so it can be reliably engaged with the engaging protrusion 71, and therefore can be correctly positioned in the contact state.

And, by rotating the recorded material collector 50 to the downstream side, the recorded material collector 50 shown in FIG. 3 and FIG. , 22b) The state of contact with the discharge driving rollers (21a, 22a).

In this way, when the recording material collector 50 is at the second position, since the paper discharge frame 40 can be in a contact state, it is possible to reliably discharge the printed paper P conveyed from the paper feeding device 2, and to reliably discharge the paper P. The discharged paper P is stacked on the recording material collector 50 .

In addition, a pinion 85 shown in FIG. 8 is installed on the matching shaft 52 arranged on both sides of the recording material collector 50 and can rotate, and a rack 86 is formed at a corresponding position on one side of the device main body. With such a configuration, the position of the recording target collector 50 can be displaced while maintaining the parallel state of the recording target collector 50 . That is, when the recording material collector 50 is displaced between the first position and the second position, the pinion 85 moves while meshing with the rack 86, so it can be aligned with the left and right ends of the recording material collector 50. Synchronous moves by the same amount. Therefore, there will be no problem that the recorded material collector 50 becomes non-parallel and difficult to move.

As described above, the printer 1 has a paper discharge frame in which the paper discharge frame 40 holding the paper discharge driven rollers (21b, 22b) is displaced between the contact state and the separated state by displacing the recording material collector 50 Displacement connection mechanism 100. Therefore, by setting the recording material collector 50 to the second position, the paper discharge frame 40 can be in a contact state, and printing can be performed on the paper P using the first transport path ①. 50 is a first position where the paper discharge frame 40 can be separated and printing can be performed on the rigid recording material G using the second transport path ②. In this way, it is possible to reliably print on a variety of recording materials.

In addition, when using the second transport path ② to print on, for example, a CD-R, etc., the paper discharge frame 40 is linked with the displacement of the recording material collector 50 and becomes a separated state, so the paper discharge driven rollers (21b, 21b, 22b) Printing is performed without contacting the CD-R or the like.

In addition, the position of the recording material collector 50 is displaced by the user, and the paper discharge frame 40 can be displaced to a corresponding state, so the operation is very easy, and there is no need to worry about operation errors, and the device structure is also simple.

<3. The structure of the transmission driven roller displacement connection mechanism and the roller interval displacement connection mechanism>

Next, the conveying driven roller displacement connection mechanism and the roller interval displacement connection mechanism will be described.

Here, FIG. 9 is a perspective view of main parts for explaining the conveying driven roller displacement connection mechanism 200 and the cylinder interval displacement connection mechanism 300 of this embodiment, and FIG. Main part perspective view, FIG. 11 is a main part perspective view for explaining the roller interval displacement connection mechanism 300, and FIGS. Main part side view.

9, 10, and 12 show the situation at the second position, and FIGS. 11, 13 and 14 show the situation at the first position. The conveying driven roller displacement connection mechanism 200 and the cylinder spacing displacement connection mechanism 300 described here are arranged on the side opposite to the above-mentioned discharge frame displacement connection mechanism, that is, the recording material when the printer 1 is viewed from the front side of the device. Collector 50 to the left of the device. That is, FIGS. 9 to 14 are diagrams when the printer 1 is viewed from the left side.

As shown in FIG. 9 , the printer 1 has a conveying driven roller displacement connection mechanism for separating the conveying driven roller 19 b from the conveying driving roller 19 a by oscillating the conveying driven roller holder 18 by operating the operating lever 32 as the operating part. 200: Displace the carriage guide shaft 12 by interlocking with the position of the recorded material collector 50, and adjust the distance between the recording head 13 and the cylinder 28 carried on the carriage 10 supported on the carriage guide shaft 12, that is, the cylinder The roller interval displacement connection mechanism 300 of the interval (PG).

First, the conveyance driven roller displacement connection mechanism 200 will be described with reference to FIGS. 9 and 10 . Here, FIG. 9 is a perspective view of the main parts of the printer 1, showing the conveying driven roller displacement connection mechanism 200 and the cylinder interval displacement connection mechanism 300. FIG. 10 is a perspective view of the main parts of the printer 1 viewed from a different angle from FIG. , represents the conveying driven roller displacement connection mechanism 200, and the roller interval displacement connection mechanism 300 is omitted.

The conveying driven roller displacement connection mechanism 200 has an operating lever 32, a third conveying member 33, and a fourth conveying member 34 provided as an operating portion on the left side (recording material collector 50) of the device front.

The operating lever 32 can swing about 90 degrees around the swing shaft 32a. A rod-shaped third transmission member 33 is attached to the operation lever 32 through a fitting portion 33a formed on a main body portion 32c on the upstream side thereof. Moreover, the 4th transmission member 34 is attached to the 3rd transmission member 33 via the engaging part 33b, and the said cam rotation shaft 31 is fixedly attached to this 4th transmission member 34. As shown in FIG. In addition, the operation lever 32 is slightly leaned toward the upstream side (apparatus main body side) by an unillustrated leaning member (for example, a rubber material), thereby restricting unnecessary swinging.

Through such a structure, through the operation of the operating lever 32, the cam rotation shaft 31 is rotated by the third transmission member 33 and the fourth transmission member 34, resisting the abutting force, the conveying driven roller bracket 18 is shaken, and the conveying driven roller 19b is away from the conveyance drive roller 19a.

That is, when the operating portion 32b of the operating lever 32 is rotated to the upstream side (inside the device), the conveyance driven roller bracket 18 is brought into contact with the above-mentioned abutment member, and the conveyance driven roller 19b and the conveyance drive roller can be moved to a state of being in contact with each other. 19a contact (see Figure 1). In addition, when the operating portion 32b of the operating lever 32 is rotated to the downstream side (the front side of the device), the abutment force can be resisted, the conveying driven roller bracket 18 is shaken, and it becomes a separated state, and the conveying driven roller can be moved forward. 19b is away from the conveyance drive roller 19a (refer FIG. 2).

In addition, the main body part 32c of the operation lever 32 is arrange|positioned in the space part formed inside the operation member 90 mentioned later. With such a structure, when the recording material collector 50 is located at the second position, the operation of the operating lever 32 is restricted, therefore, the movement of the conveying driven roller displacement connection mechanism 200 is restricted, and the conveying driven roller is maintained in a contact state. Bracket 18. In addition, the operating lever 32 can be operated only when the operating member 90 moves upward as the recording material collector 50 becomes the first position.

Next, referring to FIG. 9 and FIG. 11 , the drum spacing displacement connection mechanism 300 will be described. Here, FIG. 11 is a perspective view of main parts of the printer 1 , showing the roller interval displacement connection mechanism 300 , and part of the conveyance driven roller displacement connection mechanism 200 and the guide cover 96 are omitted.

The cylinder interval displacement connection mechanism 300 has: a working part 90 supporting the engagement shaft 52 protruding sideways from the recording material collector 50 , a first transmission part 91 , a second transmission part 92 , and a rotating body 93 .

The operating member 90 has a first side portion 90a on the side of the recording material collector 50 and a second side portion 90b on the outside, which are arranged parallel to each other, and is arranged in a convex "U" shape when viewed from the downstream side. Furthermore, the engagement shaft 52 is supported on the first side portion 90a, and is interlocked (followed) with the recording material collector 50, and can be displaced in the vertical direction of the device. In addition, a movement path of the engaging shaft 52 is formed on the wall portion 96b of the guide cover 96, which is omitted in FIG. In addition, unnecessary movement of the working member 90 along the inner surface of the guide cover 96 in the front-rear direction of the device and in the left-right direction of the device is restricted.

In addition, the second side part 90b of the working part 90 is mounted with a "V"-shaped first transmission part 91 in a three-side view through the matching part 91a, and it can swing around the swing fulcrum 91b as a fulcrum. In addition, the swing fulcrum 91 b is supported by the guide cover 96 so as to be swingable. In addition, the linear second transmission member 92 is attached to the first transmission member 91 through the fitting portion 92a, and the rotating body 93 is attached to the second transmission member 92 through the fitting portion 93a having a predetermined gap. The rotary body 93 supports the carriage guide shaft 12 at a position deviated from its own rotation center via an eccentric bush 94 .

With such a structure, through the displacement of the recording material collector 50, the rotating body 93 can be rotated by the working member 90, the first conveying member 91 and the second conveying member 92, and the position deviated from the rotation center of the rotating body 93 can be changed. The supported carriage guide shaft 12 is displaced in the vertical direction of the device. Thereby, PG can be adjusted.

That is, when the recording material collector 50 is at the second position, the carriage guide shaft 12 is displaced vertically downward (that is, the direction approaching the roller 28), the carriage 10 is at the N position, and the distance between the rollers is adjusted to PG. Normal, in addition, when the recorded material collector is at the first position, the carriage guide shaft 12 is displaced vertically upward (that is, the direction away from 28), and the roller interval is adjusted to PG++ by making the carriage 10 to the ++ position .

Thus, by adjusting the roller gap according to the recording material, the distance (paper gap) between the recording surface of the recording material and the recording head 13 can be adjusted appropriately regardless of the thickness of the recording material, so that good print quality can be obtained. Also, when the recording material is a rigid recording material G such as a thick CD-R, by setting PG++, contact between the rigid recording material G and the recording head 13 can be avoided.

In addition, a sensor (not shown) is provided near the rotating body 93 , and by detecting the rotation of the rotating body 93 , the position of the carriage 10 can be recognized.

Here, the operation of the transport driven roller displacement connection mechanism 200 and the roller interval displacement connection mechanism 300 will be described with reference to FIGS. 12 to 14 . Here, FIGS. 12 to 14 show the conveyance driven roller displacement connection mechanism 200 , the roller interval displacement connection mechanism 300 and the recording material collector 50 . In addition, for convenience of explanation, the operation of the recording material collector 50 will be described, and the displacement of the recording material collector 50 from the second position (see FIG. 12 ) to the first position (see FIGS. 13 and 14 ) will be described. In the overall state of the printer 1, refer to FIG. 1 and FIG. 2 as appropriate.

When the recording material collector 50 is at the second position as shown in FIG. 12, the carriage guide shaft 12 is maintained to make the carriage 10 at the N position, and the conveyance driven roller holder 18 is maintained in a contact state (refer to FIG. 1 ). In addition, as described above, the discharge frame 40 becomes in a contact state.

In addition, operation of the operating lever 32 is restricted by the working member 90 . That is, the operating member 90 restricts the main body portion 32c of the operating lever 32 from above, thereby restricting the rotation of the operating lever 32 . Therefore, the operation lever 32 cannot be operated to make the conveying driven roller displacement connection mechanism 200 work. Therefore, when the recording material collector 50 is in the second position, the conveying driven roller holder 18 is positioned so that the conveying driven roller 19b contacts the conveying roller. Contact state of the drive roller 19a.

From this state, once the recording material catcher 50 is rotated toward the main body of the apparatus about the engagement shaft 52 (counterclockwise in FIG. 12 ) to a nearly vertical posture, it is lifted upward.
