Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is an electronic device, particularly an electronic device that has a built-in movable mechanism that requires a predetermined operating space during operation, and also connects cables for power supply or signal input/output from the device. The present invention relates to an electronic device having a structure for direct derivation.

[Prior Art] Conventionally, there have been recording devices such as printers and electronic typewriters as examples of the above-mentioned devices. Many of the recording mechanisms of these devices perform recording by scanning a carriage equipped with a recording head along a recording medium loaded on a platen or the like.

On the other hand, among devices of this type, devices that are driven by a commercial AC power source are known in which the power cord is directly attached to the device housing. With a structure in which all types of cables, not just power cords, are led out directly from the device, there is no risk of cables being lost, and there is no need for various parts such as connectors, so manufacturing costs are low. Particularly in portable devices, etc., a mechanism is required to store the cables that are directly taken out.

FIGS. 4 and 5 show the structure of a portable electronic typewriter as an example of the above-mentioned recording device.

FIG. 4 shows the electronic typewriter with the hood F open. As shown in the figure, the printer section is composed of a platen P that holds a recording medium and conveys it in the direction in which the recording lines are arranged, and a carriage C that can scan along the platen P on a guide bar GB.

A recording head 1 of a predetermined type (type impact type in the illustrated apparatus) is mounted on the carriage C, and this recording head 1 prints onto a recording medium (such as paper) on a platen P via an ink ribbon stored in an ink ribbon cassette 2. ). The front side of the printer section is a keyboard for manual input, and the power switch S is on the right side of the device.
is provided.

FIG. 5 shows a sectional view of the device of FIG. 4. As shown by the two-dot chain line in FIG. 5, the outer shape of the carriage C occupies a fairly large area in the longitudinal section of the device.

Since the carriage C performs recording scanning over the entire length of the platen P (FIG. 4), it is necessary to secure a considerably large space in the area in front of the platen P.

Inside the working space of this carriage C on the rear side of the device,
A power supply unit 3 is arranged. The power supply unit 3 transforms, rectifies, and stabilizes a commercial AC power supply to generate a DC power supply voltage required by the device.

In order to input commercial AC power to the power supply unit 3, a power cable 4 is directly extended from the back of the device. Since this cable gets in the way when the device is carried around, conventionally a storage chamber 4b is provided at the back of the device as shown in the figure, and the cable 4b is stored in the cable storage chamber 4b when not in use or when carried.
I was trying to store it. The cable storage chamber 4b is covered by an openable/closeable M4a.

On the other hand, as a consideration when carrying and transporting the device, please refer to Section 6.
A carriage fixing structure as shown in the figure is known.

The carriage C is supported by the guide bar GB shown in Fig. 4 so as to be able to slide left and right, and can be moved to a predetermined digit position via a belt (not shown), but when the power is turned off. Then, this carriage would be able to move freely due to impact, acceleration, etc.

In such a mechanism, the carriage C may move during carrying or transportation, which may cause the recording head to become misaligned or damage the mechanism. The stopper 5 is supplied as a separate member, and when carried, the carriage C is brought to the end of the scanning path as shown in FIG. 6, and the stopper 5 is fitted between the locking member 5a and the carriage C to move the carriage C. Mechanisms to prevent this are being considered.

[Problems to be Solved by the Invention] In the conventional structure as described above, it is necessary to provide a cable storage chamber 4b that does not contribute to the original function of the device just to store the cable 4, which is inefficient in terms of space and makes the device There was a problem with the overall size. Furthermore, in order to lock the carriage C when being carried, it is necessary to provide a stopper 5, which is a separate member, resulting in an increase in the number of parts. Furthermore, since this stopper is a separate member from the main body of the device, there is a possibility that it may be lost or forgotten to be attached.

An object of the present invention is to solve the above-mentioned problems and provide an electronic device in which directly protruded cables can be stored in a space-efficient manner, and movable members can be fixed easily, inexpensively, and reliably when carried.

[Means for Solving the Problems] In order to solve the above problems, the present invention includes a built-in movable mechanism that requires a predetermined operating space when the device is operated, and a cable for power supply or signal input/output. In an electronic device having a structure in which the cable is directly led out from the device, a collapsible storage member is provided in the operating space of the movable mechanism to store the cable, or the cable storage member is configured to store the cable. In this state, the movable mechanism is fixed at a predetermined position.

[Function] According to the above configuration, the cable can be stored in the operating space of the movable mechanism, which becomes a dead space when the device is not in operation.
Furthermore, the storage member can lock the movable member so that it does not move.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings. In the following, a typewriter similar to the conventional example will be used as an example, and members similar to or corresponding to the conventional example will be denoted by the same reference numerals, and detailed explanation thereof will be omitted.

FIG. 1 shows a perspective view of an electronic typewriter employing the present invention. Figure 1 shows the hood F of the printer section, similar to Figure 4.
It shows the open state.

The difference between FIG. 1 and FIG. 4 is that a cable storage section 8 is provided by utilizing the left side of the scanning path of the carriage C, which was conventionally a dead space. This cable storage section 8 includes an inner cover 6 that is connected to the bottom of the device at a hinge H2, and a hinge H2 at the end of the inner cover 6.
an inner cover 9 joined by 1; The hinges H1 and H2 may be of various constructions, such as a known hinge mechanism, such as one using a pin and a through hole, or one in which the inner cover 6.9 and the bottom of the device are integrally formed via a thin, elastic joint. can be used.

That is, the cable storage section 8 is of a foldable type, and the cable 4 can be stored therein when the carriage C does not need to perform recording scanning and is not in use. Further, when the inner cover 6.9 is raised as shown, the carriage C can be fixed at the right end of the scanning path by its right end. Further, during operation, the recording scanning path of the carriage C can be secured by pulling out the cable 4 from the cable storage section 8 and folding the inner cover 6.9.

Hereinafter, the above cable storage structure and its operation will be explained in detail with reference to FIGS. 2 and 3.

As shown in FIG. 2A, another cover 7 is provided outside the inner cover 6.9. This outer cover 7 is connected to the bottom surface of the apparatus by the power supply unit 3 and is rotatable. A latch portion 7a is provided at the tip of the outer cover 7, and when the outer cover 7 is in a closed state, the latch portion 7a can lock the outer cover 7 to prevent it from being opened inadvertently.

Similarly, a latch portion 9a is provided at the tip of the inner cover 9, and this latch portion 9a engages with the inner surface of the outer cover 7 or a predetermined portion on the bottom of the device, and the inner cover is in the position shown in FIG. 2(A). 6.9 can be fixed. In this operating state, the cable 4 is pulled out to the outside of the device via the opening 0 (see Figure 1) provided at the rear of the hinges H2 and H3, connected to a commercial AC power outlet, etc., and connected to the power supply unit. Power is supplied to 3.

Note that rubber legs G are provided on the bottom of the device, and the cable 4 is led out through a gap in the bottom of the device, so that the installation state of the device will not become unstable due to the cable. Further, the hinges H2 and H3 may be configured coaxially.

When storing or carrying the device, the cable 4 is stored in the cable storage portion 8. In this case, as shown in FIG. 2(B), the latch portion 7a of the outer cover 7.9,
9a and pull the inner cover 6.9 inward. Further, the entire cable 4 is drawn into the inside of the device through the opening 0.

Then, as shown in FIG. 2(C), the outer outer cover 7
, and lock it with the latch part 7a. Then, bend the inner inner cover 6.9 so as to create a space having a triangular cross section as shown in the figure, and push the cable 4 into the latch portion 9 at the tip of the inner inner cover 9.
a to a latch part 7a provided at a predetermined position inside the outer outer cover 7.
The cable 4 can be stored here.

In this state, as shown by diagonal lines in FIG.
．． 9 rises to occupy the entire left half of the scanning path of the carriage C, and its right end locks the left end of the carriage C to prevent the carriage C from moving.

According to the above configuration, a foldable cable storage section is provided in the scanning path of the carriage, which is a completely dead space when not in use, and the cable can be stored here when being transported or not in use. This improves space efficiency.

As is clear from the comparison between FIG. 2 and FIG. 5, according to this embodiment, there is no need for a dedicated cable storage room, which is conventionally required, so that the entire device can be made more compact. In addition, the cable storage chamber configured in the carriage scanning path also acts to restrict the position of the carriage C, and the carriage C may be moved and damaged due to force applied from outside the device when being carried, or the mechanism may be damaged. This prevents alignment from going out of order.

In the above example, the carriage C is fixed in the cable storage chamber when not in use, but the pail roller arm 11 is a movable member that should be fixed when the device is transported or carried.

An embodiment in which the pail roller arm 11 is fixed is shown in FIGS. 7 and 8.

In both figures, a pail roller arm 11 is slidable left and right and rotatably mounted on a plurality of pail rollers ll.
r, and is swingably supported by the side plate F1 of the frame via a shaft lie (the support mechanism on the right side is not shown). The pail roller 11r can be pressed against and separated from the platen P by swinging the arm 11, and has the function of bringing the recording medium into close contact with the platen P.

A locking member 11a is fixed to the tip of the shaft 11c that projects inside the side plate F1. The locking member 11a has a trapezoidal cam-like locking portion fib, and this locking portion 11
The side of the tip b is formed so that when the pail roller llr is brought into close contact with the platen P, if the inner cover 6 is upright as shown in FIG. 8, it will come into close contact at the same angle as the slope of the cover 6.

With such a configuration, when the inner cover 6.9 is placed in the same line as described above and raised as shown in FIG. 8 to accommodate the cable 4 when the device is not in use, the pail roller arm 11 brings the pail roller llr into close contact with the platen P. If you are
The locking portions of the inner cover 6 and the locking member 11a are engaged, and the pail roller arm 11 is fixed in its swinging position so as not to move. On the other hand, when the pail roller arm 11 separates the pail roller llr from the platen P, the tip of the engaging portion flb of the locking member 11a is connected to the inner cover 6.
gradually pushes up and swings the pail roller arm 11 to a position where the pail roller fir comes into close contact with the platen P,
Fix it in that position.

According to the above configuration, the pail roller arm 11 can be securely fixed together with the carriage C, and damage and misalignment of these members can be prevented. It goes without saying that the cable storage operation has exactly the same effect as the previous embodiment.

The above example shows an example of an electronic typewriter, but
The above configuration can be applied to various electronic devices that have various movable mechanisms, and in which the operating space of the movable mechanism becomes a dead space when carried or at rest. Furthermore, it goes without saying that the cables stored in the storage chamber are not limited to power cables, but may also be cables for connection with other devices.

[Effects of the Invention] As is clear from the above, according to the present invention, a movable mechanism that requires a predetermined operating space during operation of the device is built in, and a cable for power supply or signal input/output is led out directly from the device. In the electronic device having a structure, a storage member configured to be foldable is provided in an operating space of the movable mechanism to store the cable, or the cable storage member is configured to be able to accommodate the movable mechanism in the storage state of the cable. Since the mechanism is fixed in a predetermined position, the cable can be stored in the operating space of the movable mechanism, which is a dead space when the device is not in operation, and the storage member locks the movable mechanism to prevent it from moving. In addition to improving the space efficiency of the device and making it possible to reduce the size and weight, the movable mechanism can be reliably locked by the storage member, which has excellent effects such as preventing damage or malfunction during carrying or transportation.
