[Prior Art] Conventionally, in the case of content presentation and presentation using a liquid crystal projector or the like, a laser pointer is used to indicate a reference portion (chart, etc.) of the content projected by the projector. The laser pointers used for this purpose are usually • pen type or a simple laser pointer for use on the hand. However, in the past, most of the simple laser pointers have been battery-powered and have been published in the inner valley and the highest level of the singularity of the battery has been caused by the sudden stop of the battery function. Furthermore, there are also problems with battery replacement that are quite complicated. As a countermeasure, there is a need for a circuit or a component for keeping the battery as long as possible, and there is also a problem in terms of cost. Moreover, since the simple type of laser pointer needs to be used on the hand, it is operated due to an error in the publication. Laser light may be inadvertently shot into the eyes of the audience, or in situations other than content presentations and speeches, such as when the child is used on a hand as a toy, there may be laser light shining on the eyes. As a safety measure for such problems, a commercially available laser pointer, a light output of a low laser. However, when such low-output laser light is incident on the eye, there are still various effects. Therefore, in the past, some people have adopted the corresponding measures as follows. For example, in Japanese Laid-Open Patent Publication No. Hei 10_4228, the light from the screen is collected by a lens, and during the concentrating, the laser pointer is used to make the laser pointer 125161.doc 200835937 switch: regenerative energization 'in the non-aggregation from In the case of the light of the screen, the switch is powered off' to prevent accidents caused by the erroneous operation of the laser pointer. In Japanese Laid-Open Patent Publication No. 2003-29204, there is a laser light-emitting element, a human body sensing sensor that senses heat generated by a human body in a projection direction of laser light, and an infrared sensor that emits infrared light and receives reflected light. The projection of the laser light is regulated when the human sensory sensor detects the human body in the direction in which the laser light is projected, or the infrared sensor does not receive light.

Direction to prevent false illumination of the laser light. As described above, the conventional laser pointer has problems in that it is necessary to suppress unnecessary power circuits and components for power consumption in order to cope with sudden function stop and complicated battery replacement. Furthermore, in an attempt to cope with the possibility that laser light may be incident on the human eye due to erroneous illumination, any situation requires a special device such as a sensor and has an increase in power consumption or an increase in cost. . In addition, as long as it has a function of emitting laser light by a laser pointer, even if the conventional countermeasures are performed, there is still a case of false illumination. [Summary of the Invention] The purpose of this month is to provide a kind of laughter table 4, even if the power function is stopped when the content is published or speeched, and when the laser light is not emitted, the content can be quickly responded to. Laser pointer. Further, it is an object of the present invention to provide a laser pointer which can prevent an accident of illuminating a person with a laser light and causing a human eye.

In addition, it is also easy to charge when the power of the power supply unit is lowered. The laser pointer of the present invention may also include a discharge circuit in its circuit for discharging the remaining charge of the power supply portion. Regarding the problem that laser light is incident on the human eye due to an erroneous operation of the laser pointer, etc., it is possible to cope with the conventional countermeasures as described above, but as long as the power supply unit functions, there may be some unintentional operation or accidental The accidental illumination of the laser light. According to the laser pointer of the present invention including the discharge circuit for discharging the residual electric charge of the power supply portion, the residual electric charge can be forcibly discharged by the switching operation when the use of the laser pointer is completed. The laser pointer that loses the residual charge will not illuminate the laser light, even if it operates. In the case where it is necessary to use it again, as described above, it can be quickly charged by being connected to a personal computer or the like, so that the state in which it can be used immediately can be restored. The discharge of the remaining charge of the power supply unit can also be naturally (i.e., slowly) without the use of the switch operation without the use of the laser pointer by connecting the light-emitting portion and the power supply portion via a resistor in advance. With natural discharge, the discharge can be completed as long as it has passed a certain period of time.

In addition, the discharge circuit that discharges the remaining charge of the power supply unit by e, or the light-emitting portion and the power supply unit are connected in advance via a resistor, and the remaining charge can be discharged when the laser pointer is used to prevent the laser light from being erroneous. Irradiation. [Embodiment] Hereinafter, the present invention will be described in more detail with reference to the drawings. As an example, Fig. 1A schematically shows a perspective view of a laser pointer of the present invention, and Fig. 1B schematically shows a partial cutaway view thereof. This laser pointer has a light-emitting portion i for irradiating laser light, a switch unit 2 for controlling power supply to the light-emitting portion, a power supply unit 3 for supplying electric power, and an external electronic device or source (not shown). The connecting portion 4, the light emitting portion 丨, the switch portion 2, and the power source portion 3 are housed inside the casing 5. The light-emitting unit 丨, the switch unit 2°, and the power supply unit 3 in the casing 5 are connected by wires. However, for simplification of illustration, the wire connecting portions are not shown. The light-emitting portion 1 of the circuit lb is formed by a semiconductor laser light-emitting element la, 125161.doc 200835937. The laser-emitting device 1& can use a semiconductor beam that is typically used in a laser pointer to emit 7L pieces of light. The light-emitting surface 7 of the element "exposed front end portion 8 of the frame 5 is 8°. The switch unit 2 is externally controlled to supply electric power from the power supply unit 3 to the light-emitting unit i', and the switch 2a capable of performing the power-off operation is required, and The circuit 2b is constructed. The power supply unit 3 is composed of an electric double layer capacitor. The advantage of the electric double layer capacitor, which is capable of rapid charge and discharge, and the high charge and discharge efficiency, can be an advantageous power source for a simple laser pointer. In Fig. 1B, although two electric double layer capacitors are used, the number of electric grids used is determined by the voltage and capacitance required for the laser light emitting element 1 a, and two or more cases are connected. Used in series. The electric double layer electric grid used can be either a wound type or a laminated type. The capacitance of the electric double layer capacitor is preferably 2 〇 F / or less, more preferably 〇 11 ? / 〜 20 F / piece, preferably 〇 1 F / piece ~ 1 〇 F / piece. In an electric double layer capacitor of 2 〇 F or more, it takes a long time to complete the charging, and sometimes it cannot be restored to a state in which the content is published and the speech can be used immediately, which is inconvenient. The power supply unit 3' can be provided with a discharge circuit 9 that discharges electric charges accumulated in the electric double layer capacitors 3a and 3b. The discharge circuit 9 can forcibly discharge the capacitors 3a, 3b by connecting a switch (not shown) different from the switch 2a for controlling the detection of the laser light to the discharge circuit $. As a result, after the use of the laser pointer, the remaining charge remaining in the electric double layer capacitors 3a and 3b is forcibly discharged, and the power supply unit can be prevented from functioning, thereby preventing the laser light from being erroneously photographed by I25161.doc 200835937. Alternatively, it may be naturally (slowly) discharged by the light-emitting portion 1 that can be switched on and off via the power supply unit. By discharging the electric double layer capacitor from the natural discharge, the discharge can be completed as long as it passes. In this way, the _ ^ 疋 inch, the light neighbor, so ... the charge of the source will not be supplied to the first and therefore can prevent the false discharge of the natural discharge when using the electric crying voltage VUV... The electric double layer capacitor used The voltage V1 (V), the capacitance C (F), the \nr\nm jl voltage T (s), and the final voltage V2 (V) are calculated by the following equation. R=T/(C · In(Vl/V2)) The laser pointer of the present invention can be forcibly or naturally discharged by J. Kakuda, even if it cannot be used in content publication, it can also be used. The electric double layer capacitor is rapidly charged, so it can be recharged by connecting to a personal computer, and can be used immediately. The connection portion 4 for connection to an external electronic device or a power source (not shown) can be connected to an external electronic circuit or a power source to charge the electric double layer capacitor 33, %, and any connection portion can be used. Among them, it is preferable to use a usb' (common serial bus) terminal from the connection with a personal computer that is commonly used for content distribution. Thereby, it is possible to connect to the personal computer in the content distribution, and it is easy to charge the electric double layer capacitors 3a, 3b of the power supply unit 3. As shown in Figs. 1A and 1B, the connecting portion 4 may be provided outside the casing or may be housed in the casing in advance and taken out as necessary. The frame 5 can be made of any material such as plastic or metal. The frame 5 is 125161.doc -10- 200835937 The shape can be arbitrarily selected. A variety of shapes such as a cylindrical shape or a polygonal shape can be employed. Southern Shape In the internal circuit of the laser pointer of the present invention, a data recording circuit of a semiconductor non-volatile memory such as a flash memory or the like can be additionally used. When such a data recording circuit is included, it can be saved in the content published - (4) and other materials. X. During the period of transmitting the data by connecting the laser device including the data recording circuit to the personal computer, the charging portion of the laser pointer is charged, so that the data can be directly transferred; The shot indicator is used for content posting and the like. According to this method of use, the connection time with the personal computer is usually short, and it is not necessary to charge the excess electric quantity, so that the accident caused by the erroneous irradiation after use can be effectively prevented. Figure 2 is a laser pointer of the present invention represented by a block diagram. The laser pointer of this figure has a data recording circuit 11 connected to a personal computer or the like via a connection portion 4 of a USB terminal. Further, between the power supply unit 2 and the connection unit 4, a charging voltage control circuit 12 for controlling a charging voltage to be charged to the electric double layer capacitor of the power supply unit 2 is provided. It can be understood from the above that the laser pointer of the present invention can also have an electric double layer capacitor in the power supply unit, and the power supply from the power supply unit can be stopped when the internal disaster road is released for use or when the highest tide is used. Quickly charge and resume function in tens of seconds to several minutes. : 'The circuit with forced or natural discharge in the power supply unit, and the power supply from Up after use can prevent accidents caused by erroneous illumination of the laser pointer after use. Thanks to the USB side? As the connection unit, a is connected to the content 125161.doc 200835937, etc., and the personal computer can easily charge the power supply unit. Furthermore, since a recording circuit using a semiconductor non-volatile memory or the like can be stored in a laser & circuit, the contents of the published content can be saved, and the power supply can be charged between the data and the personal computer. .
