Abstract

PURPOSE:To change a noise to a comfortable sound to improve an environment, by providing an output device which is driven with an action signal to a movable part of a printer to generate a comfortable sound other than a printing noise. CONSTITUTION:A printing head 1 operates on the command from a printing controller 11 and a transverse-feed motor 4 operates on the command from a transverse-feed controller 12 to feed the printing head 1 transversely with printing. On the other hand, a paper feed motor 7 operates on the command from a paper feed controller 13. A music box 14 synchronously driven by the transverse-feed motor 4 is mounted on the transverse-feed motor 4. In this manner, when the transverse-feed motor 4 is actuated by the command from the printing controller 11, this actuation can induce the generation of a preferable music-box tone while the printing head 1 moves with printing. Then, a troublesome noise generated by a printer can be reduced by the comfortable sound of the music box.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer having a movable part, and particularly to a printer suitable for reducing printing noise.

[Conventional technology]

Conventionally, as a means to reduce the noise generated from a printer such as a wire dot printer, measures such as attaching a thick cover have been used in order to confine this noise inside the printer and prevent it from coming out. Another means is printing, as shown in Japanese Patent Laid-Open No. 127377/1983.

Some of the generated noise is picked up by a microphone.

There is a known proposal in which the negative phase of the noise before expansion is radiated from a speaker to cancel out the noise.

[Problem that the invention seeks to solve]

However, in the prior art described above, when a thick cover is attached, there is a problem that the printer becomes larger and heavier. Another drawback was that noise leaked from openings such as the paper outlet.

Furthermore, according to the proposal in the above-mentioned publication, the print head, which is the largest source of sound, prints while moving laterally along the platen, so the distance from the receiver is not constant and the sound is generated from the source. Since the noise is not a pure tone, there is a problem in that it is difficult to generate an effective opposite-phase amplification signal for the receiver. Furthermore, since the positions of the sound receivers are not constant, it has been difficult to achieve a sufficient noise reduction effect for these sound receivers.

On the other hand, even if sound insulation and sound absorption measures have been taken for the printer and the noise level has been reduced, there are cases where a harsh sound still remains. This problem is not only a problem of noise level, but also a problem of timbre, and is caused by the fact that people are sensitive to sounds that are sensually undesirable. In other words, there is a problem in that the annoyance caused by noise cannot be solved only by conventional noise level reduction means.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printer that can convert generated noise into pleasant sounds.

[Means for solving problems]

In order to achieve the above object, the present invention provides a printer in which a print head prints on printing paper wrapped around a platen, in which at least one of the movable parts of the printer is driven by an operation signal, It is equipped with an output device that generates a pleasant sound different from printing noise.

[Effect]

According to the above configuration, when at least one of the movable parts of the printer is driven, the output device that generates a pleasant sound is driven by the operation signal, and the annoying noise is alleviated by the pleasant sound. Can be done.

【Example〕

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

FIG. 1 shows a first embodiment of the present invention. A print head 1 installed in a wire dot printer has a horizontal feed belt 2,
This platen 5 prints on printing paper 6 wound around the platen 5 while being moved laterally along the platen 5 by a lateral feed motor 4 via a lateral feed pulley 3.
is rotationally driven by a paper feed motor 7 via a paper feed motor pulley 8, a paper feed belt 9, and a paper feed pulley 10,
The printing paper 6 wound around the platen 5 is fed, attached, and removed.

Print head 1 is a print control device! The horizontal feed motor 4 operates according to a command from the horizontal feed control device 1i12 to perform horizontal feeding and printing of the print head 1, and the paper feed motor 7 operates according to a command from the paper feed control device 13. do. The lateral feed motor 4 includes this lateral feed motor 4.
A music box 14 that is driven by and operates synchronously is attached.

According to this embodiment, the horizontal feed motor 4 is connected to the print control device 11.
When the print head 1 starts to operate according to the command, it is possible to generate a music box sound with a desirable tone while the print head 1 is moving while printing. Further, the annoying noise generated by the printer can be reduced by the pleasant sound produced by the music box.

FIG. 2 shows a second embodiment of the invention. This example is the second
The music box 15 is attached to operate in synchronization with the paper feed motor 7, and the music box 15 can generate pleasant sounds in synchronization with the paper feed operation. In this case, since the paper feed motor 7 operates while the printing operation by the print head 1 is paused, it is desirable to install it together with the first music box 14 that generates pleasant sounds in synchronization with the printing operation.

FIG. 3 shows a third embodiment of the present invention. In this embodiment, a print synchronization sound generating device 16 operated by a signal from a print control device 11 that drives and controls the print head 1 is provided to generate a pleasant sound in synchronization with the printing operation of the print head 1. It is something.

Similarly, FIGS. 4 and 5 show fourth and fifth embodiments of the present invention, respectively, in which a synchronous sound generating device 1 is operated by signals from a lateral feed control device 12 and a paper feed control device 13, respectively.
7.18 is provided to generate a pleasant sound.

3 above. 4th. In each of the fifth embodiments, the synchronous sound generator 16 is controlled by a single signal from the print control device W111, the horizontal feed control device 12, and the paper feed control device 13, respectively.
．． Although a case has been described in which the comfortable sound is generated by operating 17 and 18, two or more synchronous sound generating devices each operated by two or more signals may be provided in the same printer.

Furthermore, the pitch of the sounds generated by these synchronized sound generators may be changed to add a harmonic effect to the simultaneously generated sounds. Harmony may be added by signals from the device 12, and rhythm may be created by signals from the paper feed control device.

The pleasant sounds in each of the above embodiments are not limited to those described above, and may be any sound that alleviates annoyance by harmonizing with the inherently undesirable noise generated during printer operation.

In each of the above embodiments, a wire dot printer has been described, but the printer is not limited to this, and similar effects can be obtained even if the invention is applied to other printers having movable parts.

〔Effect of the invention〕

As described above, according to the present invention, the printer is provided with an output device that is driven by the operation signal of the movable part of the printer and generates a pleasant sound different from printing noise, so that the annoying noise generated from the printer can be eliminated. This can be canceled out by pleasant sounds, and the surroundings of the printer can be changed into an auditorily favorable environment.
