Abstract

PURPOSE:To detect recording paper size accurately without being affected with mis-operation of the operator by providing a mechanical ON/OFF switch operated by a partition plate in response to the removal or attachment of the partition plate to a mount part of the partition plate to a recording paper loading part. CONSTITUTION:When a lower end of a partition plate 4 reaches a bottom of a partition plate mount slot 5, an actuator 7a of a push switch 7 is pressed by a stroke S enabling the push switch 7 to be closed stably by the self weight of the partition plate 4. Then the push switch 7 is closed. After the partition plates 4, 4 are fitted in this way, an A4 recording paper sheet 3 is loaded to a recording paper loading part 2 between the partition plates 4, 4. When the A4 recording paper sheet 3 is loaded, a recording paper detection means is activated. On the other hand, when the A4 recording paper sheet 3 of the recording paper load part 2 is replaced with a B4 recording paper sheet, the A4 recording paper sheet 3 is removed from the recording paper loading part 2 and the partition plates 4, 4 are lifted upward (L direction) and removed. Thus, the recording paper detection means is deenergized and the push switch 7 is opened.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is directed to detecting the size of recording paper in a facsimile machine that uses roll-shaped recording and can use recording paper of different sizes. It is related to the device.

[Conventional technology]

Conventional facsimile machines generally use roll-shaped recording paper, and facsimile machines that use this recording paper can, for example, use two types of recording paper, A4 size and B4 size. Those available are known.

In this type of facsimile machine, it is necessary to input the size of the currently loaded recording paper in "2" control when recording on recording paper.

As shown in FIG. 5, the conventional configuration for inputting the recording paper size includes A4 recording paper 31 and B4 recording paper 3.
Equipped with photoreflectors 33 and 34 corresponding to 2, respectively,
There are some devices in which detection signals from the hooks 1 to reflectors 33 and 34 are manually input to the main control section 35. The photo reflectors 33 and 34 consist of a light emitting element and a light receiving element, and when A4 or B4 recording paper 31 or 32 is attached, the light emitted by the light emitting element is reflected by the A4 or B4 recording paper 31 or 32. The state in which ONL, A4 or B4 recording paper 31, 32 is mounted is detected by the light entering the light receiving element. That is, A4
If the recorder 31 is installed, the photo reflector 3
3 only is ONL, when B4 recording paper 32 is installed, both photo reflectors 33 and 34 are ONL, and when neither A4 nor B4 recording paper 31 and 32 are installed, both photo reflectors 33 and 34 are installed. is turned off.

Another configuration for inputting the recording paper size is the sixth
As shown in the figure, select the recording paper size using the slide switch 37.
Some machines require manual operation. Further, in this device, the state in which either the A4 or B4 recording paper 31 or 32 is attached is inputted using the photoreflector 36.

[Problem to be solved by the invention]

However, in the former configuration, A4 or B4
Although it is possible to detect the mounting state of the recording sheets 31 and 32, it is necessary to provide two relatively expensive flap 1 reflectors 33 and 34, which increases the cost. In addition, when using photoreflectors 33 and 34, photoreflector 3
Since the output voltage varies due to the individual variations of 3 and 34, there are problems such as the need for adjustment work.

In the latter configuration, although the slide switch 37 for inputting the recording paper size is relatively inexpensive, the slide switch 37 must be manually operated each time the A4 or B4 recording paper 31, 32 is replaced. This operation is troublesome, and due to operator error, the size of the recording paper actually loaded and the size of the recording paper detected by the main control unit 35 become different. In this case, there are problems such as the possibility of interfering with the reception operation.

[Means to solve the problem]

A recording paper size detection device for a facsimile machine according to the present invention includes:
In order to solve the above problems, roll-shaped recording paper is used, and it has a recording paper loading section into which recording paper of different sizes can be loaded, and this recording paper loading section has a partition plate for positioning the recording paper. In a facsimile machine that is detachably provided and in which the partition plate is attached or detached depending on the size of the recording paper,
The installation of the partition plate in the above-mentioned recording paper loading section has a partition plate that can be turned on and off depending on the installation and removal of the partition plate.
It is characterized by being equipped with a mechanical switch.

[For production]

According to the above configuration, for example, when A4 size recording paper is loaded in the recording paper mounting section, if this A4 size paper requires positioning by the partition plate, the partition plate is placed in the predetermined position of the recording paper mounting section. mounted in position. When the partition plate is installed, the mechanical switch is turned on by the partition plate.
It is possible to detect that A4 size recording paper is loaded. For example, when B4 size recording paper is loaded in the recording paper loading section, if the paper in the B4 chair does not require positioning using a partition plate,
The partition plate is removed from the recording paper loading section. This results in
It is possible to detect that the mechanical switch is turned off and that B4 size recording paper is loaded.

The above ON'10FF operation of the mechanical switch is linked to the attachment/detachment of the partition plate corresponding to the size of the recording paper being used, so the size of the recording paper can be adjusted without being affected by operator error. Can be detected accurately. In addition, mechanical switches are cheaper than the conventionally used photoreflectors mentioned above, so
This results in cost reduction.
