Abstract

PURPOSE:To facilitate the position adjustment of a platen roller by arranging a close contact image sensor and a thermal head to a side opposite to each other with respect to a case respectively and pressing the platen roller for the close contact image sensor to a couple of arms provided to the case with a spring. CONSTITUTION:A platen roller 19 for pressing a close contact image sensor is arranged in a direction of the arrow C via an arm 17 at both ends with a spring 21 provided to a fulcrum 18 of a case 1a. Thus, an original 2 is inserted between the platen roller 19 and a glass plate 14 of a close contact image sensor section 100 and supplied in the direction of the arrow A, characters on the original are scanned optically and converted into electric signals. Moreover, a thermal head section 200 is arranged to a rear part opposite to a signal read face of the close contact image sensor section and pressed to the case 1a in the direction of the arrow D with the plate spring 6 and a platen roller 4 for pressing the thermal head.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to miniaturization of facsimile machines.

[Conventional technology]

Figure 3 shows, for example, Mitsubishi Electric Technical Report Vo162/N011/1
988 is a schematic diagram of a conventional facsimile machine described in US Pat. No. 988. In the figure, (2) is a document, and (3) is thermal recording paper, which is usually wound into a roll.

(31) is a contact image sensor, (32) is a platen roller pressed by the contact image sensor (31)+, (
33) is a thermal head, and (4) is a platen roller that presses the thermal head (33), which are arranged so that pressing force can be obtained by springs (34) and (35), respectively.

Next, the operation will be explained. The original (2) is held between the platen roller (32) by the pressing force of the contact image sensor (31) and the spring (34). A pulse motor (not shown) or the like generates power for the ridge section that can be sent in the direction of the arrow (■), and the characters on the manuscript are read continuously. In addition, the thermal recording paper (3) is usually in the form of a roll, and the thermal head (33)
) and the platen roller (4) under the pressure of the spring (35), and is fed by a pulse motor (not shown) in the direction of the arrow ■, and the heat-sensitive recording paper is heated by the heat generating part of the thermal head (33). By coloring (3), it functions as a facsimile.

[Problem to be solved by the invention]

In a conventional facsimile machine, a contact image sensor and a thermal head are connected to separate products simply from the top, as shown in FIG. 4), thermal recording paper (3), and original (2).
Close image sensor (31) and platen roller (32)
)-g', and also transfer the recording paper (3) to the thermal head (33
) and the platen roller (4), and then the original (2).
Since the facsimile machine and the recording paper (3) are fed in the same direction, there is a problem in that there is a limit to miniaturization of the facsimile machine.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a facsimile machine that can be made smaller.

[Means to solve the problem]

In the facsimile according to the present invention, a contact image sensor and a thermal head are arranged on opposite sides of a housing, and a platen roller of the contact image sensor is pressed by a pair of arms and a spring provided on the housing, so that the entire housing is attached to the housing. It is pressed by an external spring and pressed against the platen roller for the thermal head.

[Effect]

In the facsimile according to the present invention, the contact image sensor and the thermal head are each attached to opposite sides of the casing, so the apparatus is miniaturized and the platen roller can be easily adjusted.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram according to the present invention, which can be referred to in correspondence with FIG. 3 of the conventional one. FIG. 2 is a detailed sectional view according to the invention. In the figure, (1) is the facsimile, (1a) is the housing, (2) is the original, (3) is the thermal recording paper, (4) is the platen roller for the thermal recording paper, and (6) is a fixed point outside the housing. Pressure spring provided in (5), (11)
is a photoelectric conversion element substrate, (12) is a SELFIX lens,
(13) is a lamp, (I4) is a crow, (15) is a heating element substrate, (16) is a guide, (17) is a pair of arms, (18) is a fulcrum provided in the housing (la), ( 19
) is a platen roller for original documents attached to the outside of the housing (1a). (20) is its fulcrum, (21) is its fulcrum (
18). Further, (100) is a contact image sensor section, and (200) is a thermal head section. In FIGS. 1 and 2 above, the feature of the present invention is that the document reading surface of the contact image sensor section (100) is provided on the upper surface of the housing (1a) of the facsimile (1), that is, on the opposite side of the thermal head section (200). The facsimile is miniaturized and the contact image sensor platen roller (19) and the thermal head platen roller (4) can be easily adjusted.

Next, the second operation and effect of the main components related to the present invention will be explained.

In Fig. 2, the contact image sensor pressing platen roller (19) is pressed in the direction of the arrow ◎ by the spring (21) provided at the fulcrum (18) of the housing (la) via the arms (17) at both ends. There is a device that allows you to do so. Therefore, the document (2) is placed in close contact with the platen roller (19) and the image sensor section (1).
It is held between glasses (14) of 00) and drawn out in the direction of the arrow (2) by a drive source (not shown), and the characters on the document are optically scanned and converted into electrical signals. Also, the thermal head part (
200) is arranged in the opposite direction (back side) to the document reading surface of the contact image sensor section, and has a plate spring (6) attached to the housing (la).
), the thermal head pressing platen roller (4) is pressed in the direction of the arrow ■, and the thermal recording paper (3) is fed out in the direction of the arrow ■ by a drive source (not shown), and the heating element is activated by an electronic signal from the transmitting side. The thermosensitive recording paper (3) is colored and a recorded image is obtained.

In the above embodiment, the document and the thermal paper are fed out in opposite directions, but they may be fed in the same direction.

〔Effect of the invention〕

As described above, according to the present invention, the contact image sensor and the thermal head are arranged on opposite sides of the housing, and the platen roller for the contact image sensor is pressed by a pair of arms and a spring provided on the housing. Since the casing is pressed against the platen roller for the thermal head by a spring installed outside the casing, the device can be made smaller and the position of the platen roller can be easily adjusted, resulting in high-quality facsimiles. There is.
