Abstract

PURPOSE:To prevent a recording device from malfunctioning by detecting whether a recording body is present or not when an electric power is turned on, or when a support member is attached, storing the detection result, and then stopping said detecting operation. CONSTITUTION:When the recording body 18 is replaced, a recording body unit 16 is drawn out of a case 1 to replace the recording body with a new recording body 18, and then the recording body unit 16 is inserted into the case 1. At this time, a reflection type photosensor 13 detects the recording body 18 and sends a signal, and the support member 17 also generates a signal because its projection piece 19 is at a fixed position and interferes with a transmission type photosensor 10. An electric control system operates the recording device when those signals are generated, and the device does not operate unless the recording body unit is fitted at a normal position or unless the support member 17 is attached without any recording body 19, preventing its malfunction.

Description

Detailed Description of the Invention Technical Field The present invention relates to a removable support for supporting a recording medium.
The present invention relates to a recording medium inspection method for a recording apparatus having an i section 4'A.

BACKGROUND ART 11 Conventionally, in recording apparatuses such as electrophotographic apparatuses C and 4j, it has been common to use an L-ram type recording medium. When replacing this drum-shaped recording body, a part of the device 1'''i is replaced by an equivalent of 114 degrees.
Since it is necessary to do so, one degree of skill is required, and therefore the replacement must be carried out by a service person.
There is. However, since the recording medium is a kind of erasable item,
It is desirable that they be replaced by the user in the same way as consumables such as transfer paper and toner.

In order to solve this problem, the recording medium is formed into an endless belt shape, and this endless belt "I)s '+'+

Is there something that made it easier to get rid of? In this way, when the recording medium is made into a so-called cassette (recording) 1;, the user can easily set the R:f IJ51! of the recording medium. (Is it possible to do this?) When a user who is a casual user performs a task, he or she often records [

1, or the support section is often not set at the predetermined positioning port 1.

In the above-mentioned recording device [1B], a method is known in which the presence or absence of a recording medium is constantly detected using a reflective optical sensor, for example, in order to check the presence or absence of a recording medium.

In addition, in this type of recording apparatus, a developed image is formed on the recording medium using a developer, and a transfer paper () is fed separately.
Transfer the above developed image to the paper, and then transfer the transferred image to the transfer paper]
-, etc. is performed.

As described above, it is essential to use a developer in the removing device 1'i, and since this developer is very minute, it tends to adhere to the surface of the detector described in section 2. Therefore, when the presence/absence of a recording medium is constantly detected as described above, there is also a 1f state in which the detection is performed with the developer on the surface of the detector (J'i: "t"). However, in this case, a detection error and eventually a malfunction of the entire recording apparatus il'j is caused.

Purpose In view of the above point, the present invention maintains good performance of "Ij% detection" of a recording medium, and also improves lj% detection performance of a recording device II.
The purpose of L1 is to provide a detection method that can rainproof the 'j operation.

(11tj) Hereinafter, the present invention will be explained based on drawings showing embodiments thereof.

FIG. 1 is a side sectional view of a recording device 9'' using the A-body detection Jj method according to the present invention. Feed 1 that supplies paper 2 (
A table 3 is provided. Paper feed from this paper feed tray 3 [1 towards the upper corner of the case 1 is defined as the transfer device 4; l<'t?
'j5' are arranged sequentially, and a paper discharge table 6 is provided outside the case 1 connected to this fixing block 5.

A writing system 7 is provided in a part of the case 1, and a gap 8 is formed between the writing system 7 and the paper feed table 6 (see FIG. 2). Above the gap 8, a transmission type optical sensor 10 and a synchronization mark detection sensor 11 are installed as seen from the opening 9 side.
, '+'lf electric potential: 412, reflective optical sensor 13, cleaner 14, and static eliminator 15 are arranged in il'i order.

Each of the above-mentioned j% units is for performing a predetermined recording operation on the endless belt-shaped recording body 18 of the recording body unit 16 arranged in the gap 8 as shown in FIG. The recording body unit 16 can be pulled out from the opening D9 as shown by arrow A in FIG. Also, the 12 units 18 move the 915 unit 16 as shown by arrow B. , 1 to the support part A'A17 formed by 7.

As shown in FIG.
119 or 1 was thrown. Further, the frame portion 20 is formed with a 1-, '/j' opening I-+ notch 23 for holding the shaft portions 22 of the two rollers 21. The recording medium 18 described above is wound and held on such a roller 21 . A gear 24 is mounted on the shaft on one side of the roller 21,
Power from a drive source (not shown) is transmitted to the roller 21.

FIG. 4 shows an example of an electrical control system according to the embodiment. As shown in the figure, the reflective optical sensor 13 is connected to a control circuit 26, and the transparent bright light sensor 1o is connected to the above-mentioned control circuit via an inverter 27. It is connected to the control circuit 26. This system fi

In the above-mentioned configuration of the H1 device iji, A
When replacing the barrel 18 from the normal use condition shown in FIG. 1, the recording unit 16 is pulled out to the right in the figure as shown in FIG. Then, the roller 21 is pulled out together with the recording body 18 from the frame portion 20, and the recording body 18 is separated. Next, a new record', 4! : Two rollers 2 at 18

Also, if you forget to attach the recording body 18 and attach only the support part 17, the device may become inoperable.
All you can do is prevent breakdowns.

Figures 5 to 7 (/1) show the operation control routine of the control candy 11 circuit 26 written in -1-. As shown in the figure, the flow progresses in the following order: start, initialization, recording medium check operation, other check operations, and operation cloth drive step 11. This refers to the set operation of the computer's manual output ji"i and the I10 boat.

FIG. 6 shows the flow of checking the presence/absence of the support part in and the N body when the power is turned on. In the figure, ON when the power is turned on.

FIG. 7 shows details of the recording body checking operation. First, check whether the support part is set or not.
If it is not, the support section utilization 4 is set to 1 to indicate that the support section is not available, the operation is interrupted, so-called machine busy, and the recording medium F/F is set to O.

Check whether /F is 1, and if it is not 1, check whether /F is 1. If this is 1, set the tilly counter to N
In addition, the support section (4F/F is set to O, and the delay F/F is set to 1).

If the supporting part (1/F or O) is present, check whether it is 1/F or 1, and if it is not 1, proceed to the next check, and if it is 1, subtract 1 from the content of the delay counter. Proceed to the next check.

If the content of the delay counter is O, the delay
