Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a housing for an instrument such as a temperature control device, particularly a housing having a structure in which various display sections and operation sections are installed in high density on the front, and to this housing. This relates to the program card that is stored.

<Prior Art> Conventionally, various front structures have been proposed for housings of temperature control devices and the like.

In particular, recently there has been a strong tendency for display sections and operation sections to be placed centrally on the front of the housing in order to improve visibility and operability.
Housing front structures are becoming denser and more complex.

<Problems to be Solved by the Invention> Therefore, taking temperature control equipment as an example, when trying to arrange display parts and operation parts in a high density, it is not possible to take up too much space for each part. For a series of flashing lights arranged in accordance with the number of steps in a control program, etc., if they are arranged at small intervals in a narrow area, it may not be possible to obtain sufficient visibility simply by blinking them. A problem arises.

Further, in order to arrange a large number of display units and operation units at high density in a limited space, a special structure is required.

Furthermore, due to such increased density, a structure is desired in which the settings made on the display section and operation section can be intuitively recognized in relation to blinking lights, program patterns, and the like.

The present invention has been made based on many conventional problems and demands.

Means for Solving the Problems> The structure of the instrument casing of the present invention basically consists of a case, a front frame, and a front panel, and if necessary, a transparent touch panel and a printed display are attached to these. It has a structure in which a sheet is added, and a program card is stored in this housing.

More specifically, one of the instrument casings of the present invention includes a case with an open front, and a front frame that is detachably attached to the opening of the case and has at least small holes for flashing lights arranged therein. and a front panel made of a transparent plate, which is attached to the front surface of the front frame, and on the inside thereof, a projection for an optical path is formed to be inserted into the small hole for the flashing light. Another aspect of the instrument casing of the present invention includes a case with an open front, and a case that is detachably attached to the opening of the case and has a window for a code display element and a small hole for a flashing light on the front side. a front panel that is made of a transparent plate and is attached to the front surface of the front frame and has a light passage protrusion inserted into the blinking light hole formed inside the front panel; and a front panel that is tightly attached to the surface of the front panel. a transparent touch panel for operation, which is in close contact with the touch panel, at least a portion corresponding to the window for the code display element and the small hole for the blinking light is transparent, and the touch display code and other desired codes of the touch panel are displayed at appropriate locations. Consists of a printed display sheet. Further, if necessary, a card storage section is provided in the front frame, and a program card for storing the housing containing control patterns and the like is removably stored in the card storage section.

<Function> First, in the present invention, even if a series of flashing lights etc. are arranged at small intervals in a narrow area, the lighting or blinking state can be clearly recognized due to the light passage protrusion on the front panel.

Further, in the case of the present invention, the display section and the operation section can be easily arranged centrally using a transparent front panel, a transparent touch panel, a printed display sheet, etc., thereby improving visibility and operability.

Furthermore, when storing a program card for storage in the housing, the settings made on the display section and the operation section can be intuitively recognized in relation to the flashing lights, the program card, and the like.

<Embodiment> FIG. 1 shows an embodiment of an instrument casing according to the present invention. This example shows the case of temperature control equipment.

In the figure, 1 is a rectangular case made of resin or the like with an opening at the front, 2 is a front frame made of resin, etc., 3 is a front panel made of transparent resin plate, etc., and 4 is a transparent case made of thin transparent resin sheet, etc. The touch panel 5 is a printed display sheet made of a thin transparent resin sheet, and the numeral 6 is a program card stored in the housing on which a control pattern P and the like are written.

The front frame 2 is detachably attached to the opening of the case 1. Electronic components built into printed circuit boards, code display elements, flashing lights, etc. are housed inside the front (front) side of the front frame 2 and inside the case 1, and are connected to the terminals at the rear end of the case 1. They are connected by a lead wire (not shown).

In the case of the present invention, an example of the arrangement of components on the printed circuit board side attached to the inside front of the front frame 2 is shown in FIG.

First, there are four 7-segment code display elements D1 on the top row.
is arranged, and eight slightly small 7-segment code display elements D2 are arranged directly below this. Further, on the left and right sides of the 7-segment code display element D1, there are 4 or 3 pieces each.
Square flashing lights.

, L2 are arranged above and below, and one square flashing light L3 is arranged on each side directly below the 7-segment code display element D2.
Six round flashing lights L4 are arranged in a row in the horizontal direction, and below these 16 round flashing lights L4, there are also 16 round flashing lights at appropriate intervals, and they are placed in approximately the same position. There are 16 round flashing lights arranged in a relationship, and there are 5 lights on the bottom row below.
Round flashing lights L6 are arranged.

Therefore, each of the above code display elements, , D, and flashing lights,
6, the front side of the front frame 2 is provided with the code display elements as shown in FIG.
, blinking lights, ~6, windows 7, 8 for code display elements, and small holes 9 to 15 for blinking lights are bored, respectively. Also, on the side of this front frame 2,
Many small holes 13 corresponding to 6 round flashing lights, L
．． A card storage section 16 consisting of a slit is formed in the left and right direction of the portion sandwiched between the card slots 14, and the program card 6 can be stored therein in a detachable manner from the side.

On the other hand, a recess 17 is provided at the center of the front of the card storage section 16.
A display plate 18, which cannot be seen when the program card 6 is stored but can be seen when the program card 6 is not stored, can be attached. On this display plate 18, an abbreviation 19 representing a touch part of the transparent touch panel 4 is displayed, as will be described later. That is, when the program card 6 is not stored, the position of the touch part of the transparent touch panel 4 can be determined.

The front panel 3 made of the above-mentioned transparent resin plate (a glass plate is also acceptable) is attached to the front of the front frame 2. On the inside of this panel 2, there are at least a large number of small holes 13.1 for flashing lights in the front frame 2.
16 optical path protrusions 20 and 21 are formed to be inserted into each of the four optical passages.

Further, in this example, a projection 22 for an optical path is also formed in the small hole 15 portion for the blinking light. The function of each of these light path protrusions 20, 21, and 22 is to turn on and off as shown in Fig. 3, and to sufficiently direct not only the straight light from 4 to 6 but also the reflected light to the front side of the front panel 3. The purpose is to transmit it. In particular, in the case of the 16 flashing lights L4-5, the lamps themselves are small and arranged at small intervals in a narrow space, so if there is not enough light, it will be difficult to see whether they are lit or flashing. The optical path protrusions 20 and 21 are absolutely necessary.

As shown in FIG. 4, the transparent touch panel 4 has a large number of pattern lead wire sections 23 embedded in the edge of the panel front surface 4a, and a lead section 4b extending from the upper left corner of the panel front surface 4a in the figure. , is connected to a desired portion of the printed circuit board housed in the case 1.

When installing the transparent touch panel 4, it is necessary to fold in the base of the lead portion 4b and bring the front panel 4a into close contact with the surface of the front panel 3. As shown in FIG. 14, good adhesion cannot be obtained unless special consideration is given to the folded portion 24 of the lead portion 4b, the front panel 3 side, and the front frame 2 side. In other words,
As shown in FIG. 13, the lead portion 4b is connected to the panel front 4a
If the folding line 2 is simply extended from the front edge of the panel 4a, even if you try to put the folding line 2 at the same level as the edge of the panel front 4a, the folding line 1' will tend to be formed in a part that is slightly shifted upward, and even if it is installed in this state, the folding line 2 will be placed at the same level as the edge of the panel front 4a. A beautiful adhesion cannot be obtained.

Therefore, in the present invention, as shown in FIGS. 4 and 5,
First, shallow semicircular notches 25.25 are made at the base of the folded portion 24 of the lead portion 4b, that is, at both edges of the panel front 4a, and at both edges of the lead portion 4b, which are appropriately spaced from the notches 25.25. Hook part 2 protruding in the width direction
6.26, and on the other hand, on the front panel 3 side, as shown in FIG. A lead holding piece 28 formed slightly taller is provided, and furthermore, on the front frame 2 side, as shown in FIG. In addition to extending the lead holding part 29, a pair of retainers are provided on the inner inner wall of the top plate to be engaged with the hook parts 26 and 26 of the lead part 4b, as shown in FIGS. A mating protrusion 30.30 is formed.

Therefore, first, the lead portion 4 is cut by the notch 25.25.
The folding line ℃ of b can be easily adjusted to the desired position i! (Panel front 4a
(at the same level as the edge of the and,
In this case, it is not necessary to fold it at an acute angle, but it is about the angle of inclination of the above-mentioned inclined part 27゛ (more precisely, about the angle θ formed by the outer starting point (point A) of the inclined part 27 and the outer starting point (point B) of the lead holding piece 28. ), it is reasonable and risks such as damage are avoided as much as possible. This is because this type of transparent touch panel 4
This is because the lead portion 4b can only be bent at an acute angle a few times, and repeated bending is strictly prohibited.

Furthermore, when the transparent touch panel 4 is attached, the lead part 4a is sandwiched between the inclined part 27 and the lead holding part 29 of the top plate, and between the lead holding piece 28 and the wall surface of the top plate, as shown in FIG. Furthermore, since the engaging protrusions 30.30 of the top plate are engaged with the hook portions 26.26 of the lead portion 4b, the lead portion 4b is extremely stably fixed without slippage. Also,
In the case of this transparent touch panel 4, the above-mentioned notch 25.25
The one on the corner side of the front panel 3 and the appropriate round notch 25a in a part of the other corner are formed to protrude from the surface of a part of the corner of the front panel 3 as a positioning notch. Since it is engaged with the positioning protrusions 3a..., displacement on the surface side of the front panel 3 is effectively prevented.

When installing this transparent touch panel 4, when the folding angle of the lead portion 4b is made smaller than the above θ, the front surface of the panel 4 is
a is closely adhered to the surface of the front panel 3 very well without any gaps.

In addition, in the transparent touch panel 4 of the present invention, the touch parts 31, 32, and 33 for operation are set on the code display element D2, on the program card 6 (on the display card 18), and on the flashing light. .

The printed display sheet 5 is shown in more detail as shown in FIG. 7, and desired display codes 34 and 35 are printed and displayed on portions corresponding to the flashing lights 1.3 and 6.

Note that this printed display sheet 5 and the transparent touch panel 4
In this case, apply adhesive or the like to the edges of each front face and fix it by adhesion.

Further, the program card 6 for housing storage is as shown in FIG. 8, to be explained in more detail.
6 (for example, temperature level) and a control auxiliary scale 37 (for example, time signal item) are displayed, and a control step scale 38 (time scale) is displayed in the horizontal direction, and the temperature control pattern P is described as a graph. has been done. Further, a step scale code 39 is printed and displayed on a desired part of the control step scale 38 so that the rough number of steps of the entire card 6 can be quickly grasped, and furthermore, a desired part of the control pattern P is printed with a step scale code 39 printed on the control pattern P. When stored in the card storage section 16 of the frame 2, the display plate 18 is arranged so that the position of the touch section 32 on the transparent touch panel 4 can be seen.
The same abbreviation 19' is printed in advance. Further, in the time signal item, in this example, four stages and four types of auxiliary operations can be displayed, and two types of operations are set as the shaded areas. For example, if the first item from the top is the auxiliary heater drive time, the step portion corresponding to the temperature rise of control pattern P is the auxiliary cooling fan drive time, and the second item is the auxiliary cooling fan drive time. The step portions corresponding to the time of temperature drop may be divided into diagonal line portions (color identification etc. are also possible) as shown in the figure.

This program card 6 is stored in the card storage section 1.
In the case of 6, the slit for storage is in the front frame 2.
Since it is penetrated on both the left and right sides, it can be inserted from either the left or the right.

Here, it is possible to enter the control pattern P by preparing a large number of cards with various patterns printed on them in advance, but since there are a wide variety of actual usage conditions, the user may I will write it down each time. Further, the user (setter) only needs to look at the control pattern P and time signal items and input necessary information to the temperature control device itself.

When the program card 6 thus formed is stored in the card storage section 16, a flashing light L will be displayed just above the card 6.
4 is a flashing light on the lower side, and is in a positional relationship corresponding to each control step.

Therefore, confirmation of the information set and input as described above can be confirmed by the display of the above-mentioned code display element, and at the same time, for control pattern P and time signal items, the corresponding blinking light The setting contents of the temperature control device can be visually and intuitively understood by lighting and blinking of L4 and the blinking light Ls. Furthermore, the progress state during control can be grasped in the same way.

In addition, in the above embodiment, the instrument housing is made up of a case, a front frame, a front panel, a transparent touch panel, and a printed display sheet, but in the present invention, it is made up of a case, a front frame, and a front panel, and a transparent touch panel or a printed display sheet is used. The present invention can be similarly applied to a case having a structure without a display sheet.

Further, in the front panel 2 of the above embodiment, the inner surface of the light passage protrusion 22 for flashing lights was a smooth surface, but in order to improve the brightness function, for example, the inner surface of the light passage projection 22 was smooth.
As shown in the figure, it is preferable to use an uneven surface (rough surface) 22a such as thin grooves. This uneven surface is illuminated with the flashing light mentioned above. It is also possible to provide the inner surface of the optical path protrusion 20° 21 for the purpose.

Further, although the program card 6 for housing storage in the above embodiment is a single card, it is also possible to use a card 6' having a two-fold structure as shown in FIGS. 10 to 12, for example. (In addition, it is possible to fold two or more sheets.) In the case of this two-fold structure, the front side has a control scale 36, a control auxiliary scale 37, a control step mark 138, a step scale code 39, and a transparent touch panel 4, similar to the program card 6. touch part 3
A display consisting of an abbreviation 19' corresponding to 2 is printed on the upper and lower sides, and on the back side, a 7-segment code display element Dt, which is displayed when each touch section 31 to 33 of the transparent touch panel 4 is operated, is printed on the upper and lower sides. , Character (display form!ri40...
and the corresponding character explanation section 41... A list is printed.

Furthermore, in the case of this program card 6', a folding line 42 is cut in advance in the center of the left and right sides to facilitate folding, and as shown in the figure, a folding line 42 is cut in advance in the center of the left and right sides,
A small hole 43° 43 is provided at the edge of the paper (both of which are possible), so that when the paper is folded in half, it will just butt against the paper and pass through it. This small hole 43
．． Reference numeral 43 denotes a small hole for positioning the card 6' when it is stored. For example, if a locking protrusion 3b is provided on one of the inner edges of the panel as shown in the front panel 2 of FIG. 9, this protrusion 3b and This engagement allows for easy and accurate positioning. Furthermore, since the program card 6' is also in contact with the front panel 2 side, it is possible to provide a locking projection 2a for the small hole 43, 43 on the front frame 2 side corresponding to this locking projection 3b. It is.

Also, in the case of the non-folding program card 6 mentioned above, the same control scale etc. as the front side may be displayed on the back side, or a code display element similar to the above program card 6' may be displayed.
