Abstract

PROBLEM TO BE SOLVED: To provide a means of eliminating such a disadvantage that a conventional product wherein a solar cell panel is bonded to the surface of the cover of OA machinery, for example, a printer or the like is inferior to appearance because the power of a solar cell is supplied to a machinery main body heretofore by using lead wires and a connector for electrical connection is required to bring about an increase in cost. SOLUTION: A pair of independent positive and negative hinge parts 53, 54 are provided in the cover 1 pivotally attached to OA machinery and the power of a solar cell 51 is supplied to the machinery 2 through these hinge parts.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product in which a solar cell panel is attached to a cover of office automation (OA) equipment such as a printer.

[0002]

2. Description of the Related Art Heretofore, in a product in which a solar cell panel is attached to this type of OA equipment, power of the solar cell is supplied to the equipment body using lead wires.

FIG. 6 shows an external view of a bubble jet (BJ) printer with its cover closed as an example of this type of conventional OA equipment.

[0006] In FIG. 6, reference numeral 1 denotes a cover, and a panel of a solar cell 51 is attached to a front surface of the cover. 2
Denotes a printer device main body, and H denotes a hinge portion of the cover 1. From the panel of the solar cell 51 to the device main body 2,
Power is supplied using lead wires (not shown).

[0005]

However, when power is supplied to the main body of the apparatus by using the lead wire as described above, the lead wire is seen from the outside and the external appearance is poor. However, there is a disadvantage that the connector and the like are required, and the cost increases accordingly.

[0006] The present invention has been made in view of the above-described aspects, and has as its object to provide means for improving the appearance of this type of product and for reducing costs.

[0007]

SUMMARY OF THE INVENTION Therefore, in the present invention, an object of the present invention is to achieve the above object by providing a machine for office mechanization with a solar cell as described below.

In an office mechanization apparatus provided with a cover that can be freely opened and closed, a solar cell panel is attached to a surface of the cover, and a pair of hinge portions for pivotally attaching the cover to the apparatus body are provided. A machine for office mechanization, which is made of metal materials independently of each other, and supplies power of the solar cell to the machine body through the pair of hinge portions.

[0009]

According to the structure of the present invention as described above, the pair of hinges provided on the cover can be used as the positive (+) and negative (-) terminal connectors of the solar cell panel, respectively. Unlike the conventional case, the connector of the lead wire is not externally exposed, so that the appearance is improved and the cost can be reduced accordingly.

14 is a carriage, 15 is a pickup roller, and 16 is a print head. However, a printed board and a power supply unit for controlling the BJ printer are not shown.

The hinge portion of the cover 1 will be described later in detail with reference to FIGS.

The main body 2 is mechanically composed of each of the members 3 described above.
~ 16.

<Operation> A carriage motor 3 moves the carriage 14 right and left by using the carriage belt 13, and performs a printing operation in accordance with the movement.

Reference numeral 4 denotes a purge (recovery) unit which sucks ink from the print head 16 before printing, and removes bubbles and the like which become obstacles during printing.

Reference numeral 5 denotes a paper discharge roller for discharging the paper (not shown) on which printing has been completed.

Reference numeral 6 denotes a feed roller, which feeds a sheet according to the timing of printing.

Reference numeral 7 denotes a pressure roller, which serves to press the paper so as not to float during printing.

A paper discharge guide 9 guides the paper so that the paper can be discharged smoothly.

A transmission gear 10 transmits the power of the paper feed motor 11 to the feed roller 6 and the like.

Reference numeral 12 denotes an idler pulley which adjusts the tension of the carriage belt 13 so as to be constant.

A pickup roller 15 picks up one sheet of paper to be printed by the pickup roller 15 and sends it to a printing portion.

A print head 16 ejects ink from the print head 16 in accordance with paper feeding.

The operations and timings of the above components are controlled by electrical components of a printed circuit board (not shown).

<Electric Circuit> The solar cell 51 generates electric power when it receives sunlight, and supplies electric energy to the main body 2.
The electric circuit is configured as shown in FIG. 3, and the main body 2 is connected via a pair of (+) and (−) hinges 53 and 54.
Side circuit 52.

1 and 3, reference numeral 51 denotes a solar cell;
Is the main circuit, 53 is the connector 1 (CN1), (+)
54 is a connector 2 (CN2) composed of a hinge part,
(-) It is composed of a hinge part.

The energy (current) received by the solar cell 51 from the sunlight passes from the (+) electrode to the main body side circuit 52 through the (+) hinge 53 of the connector 1 (CN1), and returns to the connector 2 (CN2). ) Returns to the (-) electrode of the solar cell 51 through the (-) hinge.

In the figure, 55 and 56 are patterns, 5
Reference numerals 7 and 58 indicate respective lead wires. Since these have no particular relation to the gist of the present invention, detailed description will be omitted.

<Hinges> In FIG. 1, the cover 1 is
It is integrated with the printer main body 2 via the hinges 53 and 54. The hinges 53 and 54 are located on the left and right as shown in the figure, and the cover 1 rotates and opens or closes via a mechanism there.
You can close it.

The cover 1 is recently made of a synthetic resin and is an insulating material. However, each hinge portion 53 of the present embodiment,
Numeral 54 is made of metal (or may be metal-plated, but it is made of metal for convenience of explanation).
And the (−) hinge 54 do not have mutual conduction.
The electric circuit is as shown in FIG.

FIG. 4 shows an example of an enlarged view of CN1 53 having a specific structure of the hinge portion. In FIG. 4, reference numeral 61 denotes a (+) hinge portion on the cover 1 side, and 62 denotes a (+) hinge portion on the main body 2 side, all of which are made of metal.
This constitutes CN1 (+ hinge part 53) in FIG.

That is, the current generated by the solar cell 51 is
The signal is transmitted to the main body side circuit 52 through the CN1 53.

The CN2 54 (not shown) is formed in the same manner as in FIG. 4, and the return current from the main body side circuit 52 in FIG.
It returns to the-(minus) side of the solar cell 51 through 54.

In the electric circuit diagram of FIG.
The configuration of the pattern connecting the + (plus) pole to the CN1 53 is easy according to the current printed board making technology, and therefore detailed description is omitted.

From the negative electrode of the solar cell 51, CN
The same applies to patterns up to 254.

(Embodiment 2) In the above description, the cover 1 of the BJ printer 2 has been described as an example of the OA equipment. However, it is needless to say that the present invention is not limited to this. As a matter of course, the present invention can be applied to an OA device, and FIG. 5 shows an example of an external view of a flatbed scanner as another second embodiment.

The gist and construction principle of the present invention are exactly the same as those in the first embodiment, and a duplicate description will be omitted.

[0039]

As described above, according to the present invention,
For example, as an example, a hinge of a cover of an office mechanized device such as a bubble jet printer is configured to be used as a connector of a solar cell, so that the external appearance of an OA device equipped with a solar cell is improved, and the hinge is improved. Can be used instead of an electrical connector, and the effect that the device can be manufactured at a correspondingly low cost can be obtained.
