Abstract

Abstract A VTR equipped with an LCD projector integral therewith, capable of eliminating the complexity of wirings and preventing degradation of video signals. The VTR includes a front screen, a rear screen disposed on a front panel of a VCR body and constructed to be openable and closable for the LCD projector projecting the image, a closing detecting unit for detecting an openable or closable state of the rear screen, an image inverting unit for laterally inverting a direction of the image to be projected onto the rear screen, the rear screen being opened when a viewer observes the image projected on the front screen, while being closed when the viewer observes the image projected on the rear screen, the detecting unit informing the image inverting means of the closed state of the rear screen, and the image inverting unit laterally inverting the image to be projected onto the rear screen upon receiving the information.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 154 words
A video tape recorder equipped with a liquid crystal display projector for projecting an image onto a front screen such as a wall surface, comprising: a rear screen disposed on a front panel of a body of the video tape recorder and constructed to be openable and closable for the liquid crystal display projector projecting the image; detecting means for detecting an openable or closable state of the rear screen; image inverting means for laterally inverting a direction of the image to be projected onto the rear screen; the rear screen being opened when a viewer observes the image projected on the front screen, while being closed when the viewer observes the image projected on the rear screen; the detecting means informing the image inverting means of the closed state of the rear screen; and the image inverting means laterally inverting the image to be projected onto the rear screen upon receiving the information.
Claim 2
Dependent Claim 36 words
The video tape recorder in accordance with claim 1, wherein the image inverting means is adapted to inversely scan a string of pulses for driving a liquid crystal display panel and thereby obtain an inverted image.
Claim 3
Dependent Claim 142 words
A video tape recorder equipped with a liquid crystal display projector for projecting an image onto a front screen such as a wall surface, comprising: a rear screen disposed on a top panel of a body of the video tape recorder and constructed for the liquid crystal display projector projecting the image; reflection means for projecting the image onto the rear screen, the reflection means being movable between a laid-down position and a stand-up position; and the reflection means allowing the image to be projected onto the front screen by the movement thereof to the laid-down position when a viewer desires to observe the image projected onto the front screen, while allowing the image to be projected onto the rear screen by the movement thereof to the stand-up position when the viewer desires to observe the image projected onto the rear screen.
Claim 4
Dependent Claim 26 words
The video tape recorder in accordance with claim 3, wherein the reflection means comprises a plane mirror and a pivot shaft for pivoting the plane mirror.
