Description

Detailed Description of the Invention (Industrial Field of Application) The present invention continuously transports a large amount of sheet-like objects such as bills and checks, and records information on the objects on a recording medium such as microfilm. Microfilm camera'4
Regarding AM41Zt ridge placement.

(Prior Art) Conventionally, as this type of device, a rotary microfilm camera as shown in FIG. 4 is known. That is,
In this microfilm camera, a sheet-like object 100 such as a check is placed in a supply section 101 provided at the front of the device.
The photographed object 100 is sent to the photographing section 103 at high speed via the conveyance section 102, and the photographed object 100 is again discharged to the discharge section 104 disposed above the supply section 100. Here, the conveyance section 102 is provided with a sensor S+ for detecting the conveyance of the subject 100 when photographing information on the subject 100 on microfilm, and based on the signal obtained by this sensor S+. Information about the object 100 is recorded on the photographic film by exposure.

Further, a conveyance guide 105 is provided above the conveyance section 102 to smoothly convey the subject 100, and this conveyance guide 105 can be opened and closed in the direction of arrow A to facilitate jam removal and cleaning of the conveyance section 102. , and can be locked in the open position.

Furthermore, a sensor S2 is provided near the transport guide 105 to detect the position of the transport guide 105 in order to prevent a jam caused by forgetting to close the transport guide 105. If this is not the case, the system detects this and sends out a signal indicating that a display or the like is to be performed.

(Problems to be Solved by the Invention) However, in such a conventional example, the object detection sensor S1 and the position detection sensor S of the conveyance guide 105 are
2 are installed separately, which increases the complexity and size of the device configuration and increases costs.

In addition, sensors S1 and S2 are exposed to dust and dirt due to the use of the device.
If paper dust or the like from the subject 100 adheres to the subject 100, the sensitivity of the subject 100 decreases, especially if the sensitivity of the subject detection sensor Sl decreases.
2 needs to be cleaned from time to time.

However, since the sensor Sl, 32 is fixed in a place that is out of reach, it is difficult to clean it.

This work was very troublesome because the conveyance unit 102 had to be disassembled to perform the work.

The sensor S l does not require such troublesome work.
* In order to make it possible to perform 52 cleanings, see Figure 5 (
As shown in a) and (b), a cleaning sheet 108 consisting of a cleaning member 107 pasted on a sheet material 106 of the same size as the subject 100 is sent to the conveying section 102 to remove dust on the surface of the sensor Sl and 32. Measures have also been devised to wipe away the dirt.

However, when cleaning the sensors Sl and S2 using such a cleaning sheet 108, this sheet 108 has to be fed into the conveying section 102 many times, and it is difficult to actually remove the deposits on the sensor surface. Furthermore, during such cleaning, the sensor S l * S
2. There was also the problem that the surface was scratched and the sensor sensitivity was reduced.
