Description

Pocket light refractive AC/DC multiple function printer

The utility model relates to the photograph printing technology field of photograph, is suitable under the multiple power supply situation, and the printing of white photograph, and can make safelight and use.

The printer that sell in existing market is made up of casing, egative film support plate, removable cover, light scatter plate, light source and switch.Above-mentioned print has following shortcoming:

1. it is single to adapt to power supply, mostly is AC power.Function is simple, can only print.

2. AC power bulb, volume is big, light quantity is strong, thereby the print time shutter is short, and accurately exposure is difficult for grasping.

3. the glass that bears egative film is simple glass, can not make light scatter form even light.

4. for making light even, be added with ground glass between light source and the egative film, the above two distance increases, thereby makes casing become big.

5. the removable cover that compresses egative film and casing have only compelling force that the above two are adjacent to for the simple hinge formula is connected.

6. when printing photograph, other adds the shading paper frame, operates more.

The purpose of this utility model provides a kind of small and exquisite improved printer, and it improves or overcomes above-mentioned all shortcomings fully, can adapt to multiple power supply, and exposure is easily grasped, and reduces the operation of print, and can make safelight and use.

The purpose of this utility model is achieved in that by battery case in the cabinet and the external power supply socket on the cabinet, to adapt to multiple power supply situation; Miniwatt direct current bulb in the cabinet, light quantity is little, and enocscope changes light source direction, has correspondingly prolonged the distance of light source to egative film, adds astigmatism plate and egative film support plate with astigmatism effect, can make light even, and exposure is accurately; Axle rod, the egative film location shading clamp on cabinet top and the euphotic cover plate of band spring, can be easily the fixing position of egative film, printing paper, and block unwanted light, thereby reduce the operation of print; Different colours active plugboard at the bottom of the replacing case can be made the safelight of red or green isochrome and use.

Accompanying drawing provides the embodiment of a utility model.

Fig. 1; Schematic perspective view of the present utility model.

Fig. 2: the schematic perspective view of egative film location shading clamp of the present utility model.

Below in conjunction with accompanying drawing the utility model is made detailed description.

As Fig. 1, the utility model is the prolate square chest, is coloured active plugboard (1) at the bottom of the case.In the casing, from after be followed successively by exposure light source (2), safety lamp (3), astigmatism plate slot (4), astigmatism plate (5), enocscope (6), self-contained battery groove (7), bidirectional final switch (8) forward.There is external power supply socket (9) in the casing left side.At the casing front upper part, directly over the enocscope, locate shading clamp (18) (seeing accompanying drawing 2) and be divided into front and back two-part printing opacity removable cover (11) for egative film support plate (10), egative film from bottom to top with astigmatism effect, two parts boundary is positioned in the middle of (14) before and after it, for hinge type connects, back shroud also has a spring (12), the outside, casing front upper part both sides symmetry that two rotating axle rods (13) are respectively arranged except that hinge is connected with casing, and its length is greater than the width of 120 type films.Gap level between the diaxon rod of every limit between gap position and cover plate and the casing top is with high.(14) big together with area printed on the film.(15) block on the limit, with long the egative film front and back can not be moved with width and film width between forward and backward two cards in limit.(16) be limit card down, about between each one, twice card width be slightly larger than the casing width.(17) be preceding card down.(16) effect of (17) is to make (14) remain on the centre position of (10).(18) egative film location shadow shield.Print process: draw back the active plugboard (1) of bottom, battery is put into battery case (7), close and close active plugboard (1); Or, connecing external power by external power supply socket (9), alternating current-direct current all can.The automatic cutout of internal power supply circuit.On draw removable cover, will be according to the selected a kind of egative film of plate dimension location shading clamp (18), be placed on the egative film support plate (10), the egative film that need are printed was inserted two axle rods (13) gap on one side successively, card (15) on the limit on both sides, insert out from diaxon rod (13) gap of another side, egative film can only move left and right extremely need printed portions, printing paper is topped on it, put down removable cover, the elasticity of the spring on the back shroud (12) makes cover plate press printing paper, egative film and egative film location shading clamp, can see that by the euphotic cover plate that puts down whether printing paper is in the tram, press the bidirectional final switch, finish exposure.

Be used as the safety lamp time spent, with at the bottom of the case forward, change the active plugboard (1) of different colours according to different situations, energized gets final product egative film board (10) with light-proof material is topped.

The utility model material therefor: the lighttight material of casing; Egative film board (10), astigmatism plate (5) have the material of astigmatism effect with white pmma, opal glass etc.; Active plugboard (1) is with dark red, the plastics of dark green isochrome, pmma material; Light source is the direct current miniature bulb, and torch 2.2～6.3V bulb of selling on the market all can; Enocscope is smooth eyeglass; Axle rod hard material; The cover plate light transmissive material; Egative film location shading clamp black hard sheet material.

Advantage of the present utility model: print is easy and simple to handle, and accurately light exposure is easily grasped, and adapts to the multiple power sources situation, and can be used as safelight.
